I recently acquired an exposed hammer double. I disassembled it and found it to be in pretty good condition, but the barrel release lever spring / assembly is missing. I'd really like to install something resemblind the original, but I'd like to have a hint on what the original actually looked like. Am I wrong to think all guns of this vintage would have similar mechanisms? I'm hoping someone can show me a diagram or photo of their gun barrel release lever spring so I can start to fabricate / install something that will work. Photo attached. I've got my fingers crossed. I'm disappointed in myself for not being able to "imagine" what the original looked like. Help.
