I went to a swap meet last week and there was a [basket case] A10 for sale. Its frame no. was ZA7R 7782 and it had a ZA10 engine in it but I cant remember the engine no. Anyway, after having a look at my dating info my stuff says that the 49' A7's had the R in the frame no. but the 50's dont. 7782 is a 1950 no. My question is could it have been a genuine rigid A10. Does anyone have factory records or any way of checking. I didnt buy it as it was basically only a frame and engine plus a few bits, no guards or tank. Would have been ok if you had the remains of another one or a heap of parts. Cheers, Brian.
