Ray Braine

Up until 1930 the way in which Belgian clubs got around the strict amatuer rules was to set their players up as cafe owners. Ray Braine, who had won 4 championships with Beerschot (Antwerp), scoring 141 goals in 142 games in his 8 year spell at the club, followed this route. The Belgian Federation then introduced a  rule that banned players from being cafe proprietors unless their parents had been in the business for 5 years.  
In 1930 Braine decided to try his hand abroad in order to earn money from football without resorting to subterfuge, He was set to join London club Clapton Orient, but the British government operated a very strict control on foreign labour, and would not consider allowing a foreign national to enter the country to work as a professional footballer. 
Braine turned instead to Czechoslovakia, joining Sparta Prague. He was very successful in Prague, winning 2 league championships and a Mitropa Cup. The Czechs offered him a small fortune to adopt Czech citizenship, but he declined, returning to Belgium in 1936.
He made 54 appearances for the national team, scoring 26 goals. 

The Jacks

This has got nothing to do with Swansea Town (or City)...

David Jack took a look at the masses of people covering the Wembley pitch on 28th April 1923 and said to his father 'If I don't get a goal in the first five minutes I'm coming off...' 
He got one in the 3rd minute. The first goal ever scored at Wembley. So every football lover should know the name of David Jack.
He was , however, part of a footballing family that shows us a great deal about the game's development in the first part of the 20th century.

Bob Jack

David's father, Bob Jack, was a Scotsman. An outside right, he started playing for Alloa Athletic as a 15 year old. Like many Scottish professionals at the time he moved to England, where he played for Bolton Wanderers and Preston North End before stepping down in class to turn out for Glossop, Plymouth Argyle and Southend United.
He had moved into management whilst still at Argyle (joining them in 1903 he became player manager in 1905) and was player manager during his 4 year stint with Southend (1906-10). On retiring as a player he returned to Plymouth, where he was in charge for 28 years (for a total of 1,093 games). In later life he carried out scouting duties for Southend (when David was managing them).

Bob Jack had three grandly named sons who were all footballers:

David Bone Nightingale Jack was one of the most well known footballers of his era.

An inside forward, he began his career at Plymouth Argyle when his father was the manager. After just one season he moved to Bolton Wanderers in 1920.  He was the club's top scorer for five of the eight seasons he was there, scoring 144 goals in 295 league matches. In 1928 Bolton were facing financial problems. David Jack then became the world's most expensive footballer when Herbert Chapman paid  £10,890  to take him to Arsenal (the previous world record was £6,550).

Rollo

Robert Rollo Jack was an inside right. 3 years younger than David, he began his career with Plymouth Argyle at the age of 20. Having made 15 league appearances he was sold to Bolton Wanderers (where he joined David) for £1500. Rollo was a fringe player at Bolton, and in six seasons  he only made 29 League appearances. In 1929 Rollo joined Clapton Orient and was a regular for 3 seasons. He drifted into non league football before joining Swindon Town in 1934. 


Donald Atrill Jack. Donald didn't reach the level of accomplishment achieved by his brothers. He was a reserve player with Argyle, also turning out for Torquay United.  He joined Bolton Wanderers in 1922, but only played for the reserves. He also served Bradford City, but was not a first team player. 

After giving up football to pursue a career in accountancy Donald played as an  amateur with Finchley. 

Wembley 1930

In the early years of its existence the FA tended to use The Empire Stadium Wembley only for the FA Cup Final, which was played there every year from 1923 onwards. 1930 was the 3rd time that the England v Scotland match had been held there. Less lucrative games against Wales and Ireland were still played at league grounds. Remarkably the England Scotland game was only the tenth football match played at Wembley in 7 years.

 Wembley Stadium ltd, (managing director the noteworthy entrepreneur Mr Arthur Elvin) was a private company. Mr Elvin had shrewdly developed the company and effectively saved the stadium from demolition following the Empire Exhibition of 1924. He was always on the lookout for attractions to maximize the use of the stadium, leading to the introduction of speedway, greyhound racing and the construction of the Wembley Arena.

In 1930 there were 4 matches played at Wembley Stadium:

5th April 1930: British Home Championships

 England 5 Scotland 2 

                                                                 (87,375)

In the previous decade England had only won 2 matches against Scotland (1920 & 27) and had not won the British Home Championships outright since 1913. The previous 2 meetings of the old rivals had seen Scotland's famous Wembley Wizards' 5-1 victory in 1928 and a 1-0 win for Scotland at Hampden in 1929. 

For the 1930 fixture England fielded 4 debutants (Strange,Webster, Crooks and Rimmer). England controlled the game. They were 4-0 up at half time thanks to Watson (2), Rimmer and Jack. Fleming pulled 2 goals back for Scotland in the second half but these were separated by Rimmer's  2nd and England's 5th. 

Line ups:

England: Harry Hibbs  (Birmingham City); Roy Goodall  (Huddersfield Town); Ernie Blenkinsop; Alf Strange  (both Sheffield Wednesday); Maurice Webster  (Middlesbrough); Billy Marsden  (Sheffield Wednesday); Sammy Crooks  (Derby County); David Jack (Arsenal(c)); Vic Watson  (West Ham United); Joe Bradford   (Birmingham City); Ellis Rimmer  (Sheffield Wednesday).

Scotland: Jack Harkness (Heart of Midlothian); Dougie Gray (Glasgow Rangers); Tommy Law (Chelsea); Jock Buchanan; Davie Meiklejohn (c); Tully Craig (all Glasgow Rangers); Alex Jackson (Huddersfield Town); Alex James (Arsenal); Jimmy Fleming (Glasgow Rangers); George Stevenson (Motherwell); Alan Morton (Glasgow Rangers).  

26th April 1930: FA Cup Final

 Arsenal 2 Huddersfield Town 0 

(92,499)

Herbert Chapman's Arsenal faced his former charges Huddersfield Town in the 1930 Cup Final. It will sound strange to modern fans that Huddersfield were the more successful of the two clubs at the time. In the six seasons from 1922 they had finished in the top 3 of the first division (winning the title three years in succession) and were appearing in their 4th Cup Final in 10 years.  Arsenal , on the other hand, had appeared in one FA Cup Final and had yet to claim any silverware of note.
Their 2-0 win thanks to goals by Alex James and Jack Lambert  was the beginning of an episode in the club's history that saw them permanently elevated to the ranks of the greats. 
Line ups:
Arsenal: Charlie Preedy; Tom Parker (c);  Eddie Hapgood;  Alf Baker;  Bill Seddon;  Bob John;  Joe Hulme;  David Jack;  Jack Lambert;  Alex James; Cliff Bastin (Manager: Herbert Chapman)

Huddersfield Town: Hugh Turner; Roy Goodall; Bon Spence; Jimmy Naylor; Tom Wilson (c); Austen Campbell; Alex Jackson;Bob Kelly; Harry Davies; Harry Raw; Billy Smith (Manager: Clem Stephenson)

So, England and Scotland, two of the World Football Superpowers, and Arsenal and Huddersfield Town, the eras most prolific club side and the rising stars in by far the most superior league in the world.
What next...
Clapton Orient versus Brentford?
Yes.
The idea of Wembley being used by the lesser lights was not a new one.
A prospective London based club (that never really existed) called Argonauts were  able to give assurances that Wembley would be their home ground when they unsuccessfully applied to the Football League in 1928, 1929 and 1930.
So, why Clapton Orient?
Orient (today's Leyton Orient) had moved into a new ground at  Lea Bridge Road (Hackney, London) at the beginning of the 1930 season. There was a problem , however. The speedway track was too close to the pitch and the pitch was already the minimum permitted width. Restructuring was necessary. Orient unsuccessfully approached both Leyton FC and Walthamstow Road about temporarily using their grounds. So Wembley it was.

22nd November 1930: League Division Three (Southern Section)

Before this game Orient were 17th and Brentford 3rd.

The Daily Herald commented unfavourably on the 'quagmire' of a pitch. There was no Zeppelin and no King George.

Orient's next game was an FA Cup replay against Luton Town that was played at Highbury, but they returned to Wembley for their next home league match:
