Looking for advice - S/42

make sure the little spring loaded pin at the end of the trigger bar is sticking out, and not stuck back in its recess...this is what contacts the trigger lever on the sideplate....you can check to see if the firing pin is not being caught and ccoked by the trigger bar by cycling the action on EMPTY chamber and shining a light down the barrel to see if the firing pin is retracted as it should be, or has ridden forward and is protruding from he bolt face

I think what nukem means here is "Sear Bar". He is correct in the operation. Sometimes the sear bar plunger will get gunked up and will stick, not pop out enough for the trigger lever to contact it. Thanks, nukem.

You guys are too good to me! :-) This is exactly why I got on here. These are the types of troubleshooting techniques I would have taken too long to finally figure out on my own. The experience of others is always priceless, and I clearly came to the right place. I'll have to wait till tomorrow evening to follow up on your advice, but it's all great! I'm excited to get to it.

I know the firing pin is good. About two years ago the owner of this piece told me his father had tossed out the firing pin decades ago to get the gun into the country. I bought him a new firing pin for his birthday. Well, as it turns out, his father had not removed the firing pin (or anything else). Since the birthday gift pin of two years ago was available, I changed it out. There was no visible damage to the existing pin, but I changed it anyway since I was in there.

I think I'm down to either the sear bar or the trigger plate, and the trigger plate is serially mismatched to the gun. The plate was replaced before I was born as an armorer's answer to some other problem. It was likely cannibalized off an inop weapon.

Thanks again, guys! I'll post how it worked out.
