Thanks for your help

Thanks for you replies. Here are some pictures if anyone can tell me more. Do the M2 and M3 models actually say "M2" and "M3", or you just know by some other way? This has a single M with a circle around it - on each side of the vise.

I purchased one of these recently, and it just has a "M" on it. I've read on this forum about a 604 1/2 not having a M anywhere, and others talked about a M2 and a M3, so what does just M mean? Any help identifying age or color or anything meaningful would be appreciated. Thanks. Mark
