Greetings all!
I've just joined and am excited to begin to sift through all of the forums. I do have a Trapdoor that I would like any information on. I have tried uploading photos but am apparently doing something wrong as each attempt ends with the: "Upload failed" message. Some of the number stampings on the gun are hard to read. I have what appears to say a "US Model 1878". The serial number looks like it reads: "373857". The first digit maybe an "8" but looks more like a "3" to me. Anyways, any insights would be appreciated. Thanks much.
