Hi all most of the ASC posts that i have found, are from around 2007 and assume you know how the basics of the ' bellows " mechbox work. I think that maybe explanations from before that are lost in space

Anyways back on topic i'm wondering how those old top m60's worked. ( i don't mean 'hey they worked crappy", i mean " part A pushed on part B resulting in ...etc". I have a chance to buy one for 2 bills~ maybe some older gentleman members can remember what i would have to do to slam a modern mechbox in one. Any info would be appreciated.
