Great image, for us NE cowboys ( i'm a new guy here just lurking and learning, thanks to you all for giving your time and your knowledge)
Based on the last pix posted the rifle is a Winchester 92 which replaced the 73
The Whitney's had round barrels I believe and the loading gate was forward on the receiver. the Win 73 had a plate on the receiver among other differences.
Thanks for posting you image
Congrats on the Marlin, I own several that I use for CAS and my favorite is a 94 made in 1894 in 38-40.
I love those old guns. Good Luck with it. Oh, by the way, first post here, I have been just lurking for a while.
