Paul, SUNBAC disbanded due to lack of members (age !) and a change in the attitude to Motorcycles in the mid to late 60's. The activities of some in the 'Cowsheds' on the parade must have helped. (see Double Zero posts). However, a few did resurrect a sort of club, the Sutton Coldfield Tudor Rose Motorcycle Club. (known amongst its detractors, me included I must say, as SCOOTERMUCK !) The guiding light was one Geoff who lived opposite the Sainsbury's car park entrance. My late brother was a member, likewise a lady Florist who lives up the road from me. I think it survived into the mid 80's.
