I think I could find an old frame and I know a welder that could take of that. But on the frame number does it look like there are grinding marks around it or just a shadow? The numbers on my early diecast (build date 12/69) frame and engine look very uniform. The auction looks like each number was individually stamped. Sandcast experts, is this the way they were? Also, was there a tag on the opposite side of the neck like mine? Is there anything else in the photos that stands out as being obvious sandcast?
Thanks,
Mark
