Disassembled Carleton Underhammer. As is common with springs, the sear spring jumped out of position as I unscrewed the plate holding the action. I am having difficulty figuring out exactly what that spins hooks to and how. You Tube is helpful for most firearms, but this is an uncommon handgun. Can anyone out there send me a picture of what right looks like? Extremely simple action, just can' figure out the damn spring. Thanks.
