Ktagman..
I always thought that the mag length chsnge happened in the early 90s as a respose to the 10 shot mag capacity restrictions in states like New Jersey etc..
I have a copy of every Marlin catalog from 1960 to 2010...
Let me check and see when the mag change happened as per the catalog specs.
UPDATE-
I just checked my catalogs..
The M60 changed from the Glenfield Brand to the Marlin m60 in 1983
Thr Bolt hold open tab was added in 1985
The first year of the shorter mag was 1992
My 1990 catalog shows the full length magazine.
1990 is probably full length but with the 19" barrel?
WHO said anything about a 19" barrel?
Not me.
Not the OP.
And not Marlin's catalogs up until the mag length change in 1992..
The guns still had 22" barrels.
Where'd you get the idea that a 14 shot tube mag conforms to a 10 shot detachable mag restriction?
Edit: I've seen plenty with the 22" barrel and 14 shot short magazine. So whether your catalogs show it that way or not, they were made.
This site says the bolt hold open happened in 85, and magazine was shortened in the late 80's. But doesn't say if that's 86, 87, 88, or 89.

Marlinowners has this thread that says it was shortened in 1990 though.
