Not quite from the moon, but the A7 has arrived at my house. Best find, thus far, frame number is year-correct with the engine. Eventually I'll confirm the pedigree with BSAOC. This bike really does give the impression of being mostly original but suffering some bumps, bruises and wierd modifications along the way. A few diappointing things, but nothing insurmountable: the mag does not spark when hand turned (no big deal), the rear mudguard was at one time bobbed-off then poorly welded back on, there is an ugly brazing repair to the rear hub sprocket, the engine is siezed. One thing about the engine being siezed, my gut feeling is that it was never loved enough to bother rebuilding and maybe this could mean lots left on crank and in bores for grinding and boring.
Oh, the surprises ahead. One other surprise: the wife is pushing for a full restoration.
