1981 Triumph TR7
Currently on SORN. Front plate carries a tag for Kitchen Brothers in Diss, not a garage I recall (the oldest Austin Rover dealership I knew of was Averill's). A quick Google doesn't show any photos or give an address, but intriguingly it apparently had a Wurlitzer organ installed there in the 1970s which came from a cinema in Newcastle. Perhaps worth investigating further at the local museum?
