A friend asked me to look at his Dad's gun and see if I could get it working. After putting a drop of SumGuy Lube for a couple of days, the rusted in sideplate screws came right out and I found that the spring that is pinned to the grip frame near the top and bears on the rear of the trigger return is broken and the mainspring is missing. Otherwise every thing appears OK. Does anyone know where to get these parts? I'd bet that any K-frame mainspring will fit, but the trigger return spring is a problem...I'll admit to not being a very good spring maker and this is a really odd one with a little tab at the bottom to fit into the frame to allow it to be pinned in.
