Good news on the Stevens Favorite. Guts are basically good. Here arranged in shooting position...at this position, cartridge is fired. Lower the lever and the triangle between lever and breech kicks the hammer back to half cock. Simultaneously, the extractor/ejector cams over the breech screw and kicks the spent shell free. Critical to these actions are the two pins that connect the breech, to triangle to lever. The design is such that when the lever is closed, the pins and their associated parts are slightly bound by being cammed just over center. These pins are serviceable but loose. I'll replace them for a better fit. Note, everything but the pins and screws is cast iron (frame) or case hardened steel (guts). Gentle work is indicated. Trigger jobs are destructive unless the parts are rehardened. These are fine, and safe in function...no need for molesting the case hardened skin on the parts. The extractor face is a bit battered...but it may be salvageable. If not I'll make an extractor (non spring loaded) by hand from cold rolled steel and case harden it after cutting the lip with a chambering reamer....If at all possilble I'll save this extractor first. But I've made dozens of extractors for these old fellas and they all are still in service years later with nairy a complaint. Other than that, there is one screw which is a bit worn. I will either have to make a new screw or retap and/or bush and tap the corresponding hole in the frame. After that, and if it shoots well as is, this will be primarily a cosmetic restoration.
