New Member. New Trapdoors.

Hello all!

New meme we here and I’m looking to see if anyone can help me figure out what these trapdoors are.
I know there’s a ton of variations and they can be hard to nail down.
Here are some pictures. They are chambered in 50-70 if that helps. They have 28” Barrels measured with a tape down the bore to the breach block.

Both are combinations of .50-70 and .45-70 parts, made up by surplus dealers such as Francis Bannerman and the like. No historical or collector value whatsoever. Sorry.
