I bet it's an 1893. The Marlin 1894s were in the same calibers as Winchester 1892s - .44-40, .38-40, etc.
I have an 1893 in .38-55. With moderate loads and hard cast bullets, it's a tack driver. I gave $25 for mine, but that was in 1961 and I stole it even then.
Gunbroker has a few from $875 to $1500, but no one is bidding.
