I'll take a photo or two tomorrow and post them on my web site. The 5C
and 5D could have been struck but they are really even, not like a hand
stamp. I wonder why it has no M marking as that is what is supposed to
be with that casting number according to the parts books I looked at
owned by the guy who gave it to me. They are similar to the X. The X
and 5C are on the same fromt counter weight but in different locations.
None of this matters to a hill of beans of course. It is gonna get used,
no matter what, lol. Curiosity drives this..
Thanks for the info on the actual par number. Iwill jump over to a part
number decoder and see what additional info it says.
