I am now the owner of a 1939 era, Sportsman. It is a bit rough on the outside, but nice on the inside where it counts. Everything seems to be in very good working order. I would like to take it apart and perhaps rust blue the barrel and certainly the cylinder, but there are an amazing number of small parts to this thing. This is well outside my comfort zone of falling block rifles and muzzleloaders. Does anyone know of a good parts diagram for these early guns?

I did find a Youtube video that is helpful, but a diagram would certainly be nice too.
