With a little help from Jim Akins, Bobby Brooke, and the NRA Firearms Disassembly book, I got the hammers out my 6$ Parker Trojan yesterday. As I expected, I had to clean up and slightly deepen the chipped notch right hammer as well as reshape the replacement sear. Did this by putting both sears on the axle outside the gun and taking the right sear nose back until a match with the original left side sear. Right barrel still cocks slightly later than left but early enuf that I don't have to force the hinge wide open to make it cock and the pull is heavier. Quite easy to compress the hammer springs and keeper and retain with a punch; didn't seem much different than the usual spring compressor approach so getting the threaded axles back in didn't present any problems Getting the rest of it back together (cocking hook and toggle and slide and trigger plate) is a conundrum but getting the trigger block to engage in the opening in the safety spring was like to having a litter of kittens. I missed engagement the first time, seized the slide and flattened the spring, had to remove trigger plate, sears and stock, pry the spring away from the tang, and then think five times about getting the pushrod, trigger block and safety spring in the correct position for hammers down. Need a safety test to make sure jaroff eliminated but otherwise I'm hopeful that this blind tinkering is an improvement on what proceeded it.
