Thanks again Pete for your reply, re-reading my comment it didn't come out well, sounded negative and not quite what I meant - sorry. I love collecting, especially BSA; typically Superstars, Challenger, Mercury S, Airsporter S, RB2, Goldstar.... and the usual foreign stuff, I was wondering about the Brum Supersport being worthy of collecting, especially a custom job and now you have cleared that up. Either by myth, or propaganda, it seemed that the Lightning and possibly the Supersport(?) had problems with spring breakages and suffering quality issues - this may be related to the foreign BSA's? Not being knowledgeable of the model and the hear-say, it had put me off somewhat, please excuse my ignorance of the Supersport. Now being more knowledgeable from the replies, a Brum Supersport is worth looking out for.

Kind regards....
