No I don't think we have met.Hello Jon, I don't think we have met, But talking of Numbers, My first Twin I bought in 1965, I think.
I still have it, But the Rear Frame numbers are really Small !!,
I have been around Vin's for many years, And never seen the like,
It was ONLY 15 years old when i bought it, And we never worried about numbers back then,
I guess it could have been in a crash and replaced,
Just saying after all these years who knows.
Dear old John Marshall used to check our numbers at the race track and rally's, He took mine so often, He had my Engine number in his head !!, But never said anything about the rear frame, He may have only been taking the Engine numbers ?. Cheers Bill.
You'll be pleased to know John Marshall's books are still giving us information to this day and Simon has been busy transcribing all his notebooks, supplied by his family, for quite a while.
A lot of rear frames were swapped smashed and of course restamped over the years. There are rear frames from differing bikes all over the place.
In the UK the rear frames are of no interest to DVLA and that's probably a good thing.
