A question on Lyman mold number

[JoeH]

I'm casting for my 38/55 from a Lyman mold #375449CV. OK, I know the 375449 is the mold number but what, if anything, does the "CV" indicate?

do you think it is that new venting that lee uses? not being sarcastic a am a little green to casting. it was a big word like colloidial venting or something. lol:confused:

It's a Lyman mold and probably 30+ years old.

Thanks, I didn't really get an answer but at least I now know I'm not alone in asking. LOL
