Rigid A10

[Brian]

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.

I thought A10s had A7 frame numbers apart from the much later RGS.

Sorry about that Fido, too many numbers to think about. It was definitely ZA7R 7782. I've changed my original post.  Brian.

I think the rigid frames were stamped "R" after the plunger frames became available, being stamped"S".
