Hello - unless I'm very much mistaken (!) I think you will find that this is indeed a 1966 model - but the infamous BSA A10 lookalike, the Kawasaki W1.
Never mind - I'm sure you'll unearth an A10 or A7 soon, I hope.

Ah ha! Here's it's cousin:

The tanks (oil & fuel) seemed off, as did the passenger peg/exhaust hanger. So much for getting a Rocket Gold Star for beer money.
So did any A7 or A10 come with full-width alloy hubs?
