Looks like 1970 barrels to me, thick flange. Does the clutch cable enter vertically or horizontally? What front brake is fitted, SLS or TLS.
after looking hard at the number and looking at the Bacon book.
A65 TA is weird, the T should represent the Thunderbolt model and the A suggest 67 , I think the A is a mistake or some other designation like a forces model or something, the XD is December 1970 by my reckoning, that fits with the embossed number area and the 1970 thick barrels. I hate to see red hermish3te on the joints, its hard to get off, paint stripper we call Nitromors in the UK I think you call it Naval jelly, will shift it, you know the stuff, it stinks and burns your skin.
