The CV prefix is correct for the D-55, but the numbers were used sequentially and the highest I've seen is in the high hundreds CV000xxx. The CV120001 would imply that 12000 D-55s were made and we know that can't be the case given Corona production was only a few years and D-55 production was low no matter what facility it was made in.What doesn't make sense to you, GG?
I think Ralf or Hans will have to figure it out.Got it. Good luck with the sleuthing!
