Hi there all, It amazes me how many genuine Vincent parts had part numbers stamped into them...Just preparing some parts for replating and noticed that even the fuel "T" piece had the part number A50AS stamped on the inner side of the "T" ...same as the footrest pivot bolts..FT84, the alloy battery hold down thumb wheel..FT130..and so on. Where did they ever find the time to stamp them all, and why did they actually do it.....when you consider most other manufacturers even to this day do not do this....Did any other manufacturers do the same thing around that era, or was this something, again unique to a high end bike such as the Vincent...? Your thoughts....anyone..Cheers...Greg.
