now from a marlin-phile......
What's difference between the Marlin 1897 and 39A (and Golden 39A)? I know Marlin lever centerfires are highly regarded, but haven't had much contact with the lever rimfire owners to get opinions.
same action, same reliability, the differences are cosmetic/ personal config preference type things.
the 1897 is the "cowboy" version, ie stright grip, octagon barrel, Marble's semi-buckhorn rear and Carbine front (no hood). basicly a .22 scaled version of the 1894CB and 1895 and 336 Cowboy models.
the 39A "golden" is the one most folks seem to have. pistol grip, hooded ramp front sight fold down rear, round barrel, usually a gold(tone or plate don't know) trigger (i have a 39M golden that has a blued trigger)
as for what to get, get a marlin!! hands down i wouldn't even consider the other .22 lever guns now that i've had a marlin.
the 39 action is the easiest i have ever seen to clean, unload and clear the gun, undo the thumb screw, separate the action halves, slide the bolt out of the "barreled" half and clean. everything is right there to be able to clean and lube. (a small screwdriver or two is handy for turning the little slotted screw that holds the ejector down, allowing acess for chamber end cleaning)
there are fewer moving parts (maybe 10 if that many, including the mag follower and spring) to wear out, break or otherwise go wrong. in fact at times it seems so simple it's scary.
I've been shooting a 39M (carbine with straight grip) for about 15 years and except for gumming up from lack of a good cleaning, i've never had a bit of trouble out of it. when i was given the gun (was a gift from my father and teh first gun that was "mine") dad and i had looked at all of the guns then on the market, of the three (same ones you mentioned, the new henry rifle Co. having not arived yet) it was just a hands down no contest decision in favor of the marlin, it just seemed more "right" in my hands than the Winchester and the browning (the browning lasted right until i cycled it and found that i didn't like the BLR's short throw lever)
but to each there own but do NOT buy one of the others without first taking a good look at the Marlin.
