winchester
I did a quick search for Winchester and came up with the following internet based from the Win Collectors Assoc...... take this for what it's worth.
-.44 mag was introduced in 1968 and discontinued in 1970, to be reintroduced in about 1982, which might coincide with angle eject era beginning....dunno
-.357 mag came later in the early '90's.
Gunsmith's were converting M92's to mag pistol calibers prior that and references to same can be found in various sources, the RCBS reloading manuals for one.
My Dad had one of the early 1968-1970 M94's, but traded same before I knew about his plans.
I'll check on Marlin later.
