Trapdoor Rifles

I just purchased an 1884 trapdoor from my neighbor. missing a front barrel band spring, barrel band and cleaning rod, but the main issue is the brass firing pin is stuck in the firing position. removed the breech, tore it apart and have had it soaking (completely submerged) for a couple days in pb blaster but its still stuck fast. any tips on getting it out? The serial number (127,197)on the receiver is way to low to be an 1884, however, the breech is marked 1884, it has the proper sights, serrated trigger and rear barrel band for an 1884?

I've had 2 1890s manufactire 1884 rifles that had low sn in 130 range. I thought they were Franken rifles untill I ran across some information about how springfeild used leftover receivers for a while. Could be correct. Also try giving a light tap on the firing pin if it is protruding from the face of the block. Sometimes if a trapdoor with a Bronze firing pin is dry fired, it will peen the soft Bronze into the firing pin hole

I had this happen recently on an 1868 trapdoor that had a broken pin and spring that were rusted in place. I had to take the block off the gun and gently drive the pin out with a proper sized punch. Then used a cleaning brush to capture the broken spring coils. Yours shouldn’t have a spring of course. I have found break free does a really good job at releasing rusted parts. It often takes several days of soaking and jigging the parts to get stuff freed up. Once you get it out make sure you remove all the rust from the channel before reassembly.

Thank you for the responses, I've got it soaking in pb blaster and sitting on top our wood pellet stove. it don't get warm enough to even melt plastic so I'm not worried about to much heat, but figured it couldn't hurt. The pin is sticking out in the fire position and recessed in were the hammer hits it, so I'm wondering if it was dry fired and smashed in. I'll keep up the soaking and fiddling and see what happens...lol Sadly I'm a sucker for a 45/70. I also have an 1873 carbine.

Give the tip a little tap a roo

If the block is peened a bit over the firing pin hole from dry firing, you may need to relieve the edges a bit to be able to remove the firing pin from the block.
