One octagonal barrel here, on a Marlin 39 "Century Limited". --Technically, I believe it's actually a 39a; but Marlin stamped them "39 Century Ltd." So that's what I go with.
...But also a big lever gun fan. Well, a Marlin lever gun fan.
A quick count shows nine currently in possession (including the 39CL). Some are projects. Some are fully functional. Some are fully customized. Some are new (2017). Some are old (I think a 1946 M36 is currently my oldest - but there was a 1906 Model 1893 for a short time).
Irregardless, ALL are lever guns and fun as hell.
.22 LR to .30-30, to .44 Mag, to .444 Marlin. Factory to full custom. I love them all.
There's also a Henry. But we don't talk about that one. I don't even let it sleep in the same safes as the Marlins...
I have great respect for the Henry, Winchester, Browning, and Savage designs (and Ruger, too, I guess). But I think Marlin's take is the best balance of utility, performance, production cost, affordability, and safety. As a 'garage gunsmith', I also appreciate how easier they are to work on, repair, and/or modify.
Big game has yet to fall to one of my lever guns.
But next year may change that. We'll see...
