Hi, I have a 39 which I started to rebuild from a basket in 1982. Did all the work myself. Since then I have heard conflicting information on my gas tank, it has what appears to be a 1940 with the shut off on top. But the original owners son I bought it from claims that was the way his dad bought it new in 39. He had bought a 1938 also after the war for a parts bike and by the time I got the bike they only saved the best parts in boxes around mid 60's. And some of them where in bad shape. This was the tank that they had, it had no holes in the side for badges or anything on it when I repainted it. My engine Number is 39EL3528 which is a high number and I was hoping some one might have a number higher then mine and let me know if their tank is the same as Willie G once told me at a show they sometimes ran out of parts towards the end or a run back then, and would use what they had available. Any comments?
