The serial number is "845017" and I am assuming with the 8 being the first digit, it is a 1968? It is what I believe to be a A65 or A77, they were made from 1968 to 1972.
it is not a 65L or 77, those serial numbers were next to the fuel hole. This serial number is placed where the 480CD/2101XP/2100CD were riveted near the muffler.
Please advise. thx.
