Hi Arthur
Got the results on the Charterhouse Auctioneers website, it is recorded as being sold for £3100.00. This does not surprise me, there is a story behind this motorcycle.
At the last moment, prior to the sale, the machine's description was changed by Charterhouse, they added that it was fitted with "a replacement engine" (it didn't have the original RAF GR engine, it has an Army GB engine fitted). They added an amendment saying it was restored to "near original specification". Also the estimate was revised down from £5000-£5500 to £3800-£4200 prior to the sale.
I have researched this actual machine in the past and I have a copy of it's RAF history (the Auctioneers/vendor stated it's history was not known).
I am unwilling to mention any more here but should the new owner be a member of the BSA Owners Club, or should any member know who it is, I would be very pleased to pass on what I know about this particular motorcycle.
