Hello John,
I believe I can give you some more information about the team Dan Gibbs has asked about. Firstly the picture of that team is named correctly apart from John Grahame is actually Alan Grahame  and the mystery rider on the end is Rob Pfetzing.
This team rode as the Brummies on 23.9. 84 against Oxford in what was billed as the Grand Opening meeting but was in fact the second speedway meeting held at Bordesley Green as a four team junior event was held on 2.9.84.
However this was the first meeting as a seven man Brummie side and they beat Oxford 41-37.
Scorers were, Brummies Neil Evitts 9, Andy Grahame 8, Simon Cross 8, Alan Grahame 7, David Bargh 5, Rob Pfetzing 4, Linden Warner 0. Cheetahs Hans Nielsen 12, Simon Wigg 10, Mel Taylor 5,  Jens Rasmussen 4, Nigel Sparshott 4, Ian Clark 2,
Nigel De`ath 0.
A second challenge match was held on 26.10.84, although it was a completely different Brummies team, against Cradley Heath which the Brummies won 40-38.
Scorers were, Brummies Hans Nielsen 15 max, Neil Evitts 7, John Jorgensen 6, Bobby Schwartz 6, Shawn McConnell 2, Ari Koponen 2, Kym Mauger 2. Heathens Lance King 11, Alan Grahame 11, Phil Collins 8, Simon Cross 5, Finn Jensen 3, Steve Collins 0, rider replacement was used for Erik Gundersen who was at an FIM dinner!
I attended both of these matches and I believe they were the only two held there that year( apart from the junior 4TT) ,although I could be wrong, it was a long time ago!
I hope this helps
Regards
