Here's one for you all.
On 07/07/1975, Birmingham staged an inter league 4TT which featured the Brummies, Newport, Ipswich and Swindon. After the main event, a second half was held. In the last heat of the night, the rider of the night final, Swindon's Martin Ashby broke the Perry Barr track record of 62.4 seconds which had been held by home skipper George Major for 2 and a half years.
Can anyone out there recall if this has happened before or since this meeting at Perry Barr as it's highly unusual for a few reasons?
