my memory is going but was this not the one that had frame cutting to remove the battery and was rejected/returned by a retail buyer somewhere? of (maybe) ten years ago?
Look at the frame tube close to the battery on right hand side., I cant quite see if the carbs are VHB or PHF but the brakes give it away as an SF1 which should have PHF's, and the big valve head, if they are VHB then likely the head is small valve. the brakes and clocks are right for SF1, it may have potential, but by golly it would have to be cheap, I quite like the period look race tank, but the seat is absolutely awfull.
