I have an 1892 in 32 CF that I have refurbished and it is a very enjoyable gun. It is a plinker, not a high power. Wisner's has some parts for the Marlin 1892, the outer tube may be sourced from Brownell's or other vendors.
The 1892 was furnished with two firing pins one for RF, one for CF. I believe Wisner's also supplies these.
The 32 is not the 32 S&W, but the 32 Colt, which is obsolete and hard to come by. There is a seller on Gunbroker who resizes 32 S&W brass and supplies cast bullets. His seller name is tenmile.
