Jimmy,

The Frame No. is going to be N122 78209. That makes it a 1958 Model 88.

thank you, that's excellent, but what does the W mean?, ive checked on the frame and there is "W12"stamped horizontally at the top, ,don't suppose its important, but would like to know..thanks jimmy, (fantastic fast response, best money ive spent joining this site)
