Model 1879 carbine

Posted by Bud on Wednesday, 30 June 2010, at 10:37 p.m.

This is my first post and I am writing to ask if anyone might provide SRS information or any other insights into an 1879 Trap Door carbine that I own. It is serial numbered: 379,764 with a 22” barrel, short-wrist trap door stock (10.5” to the comb from the rear) with key-hole butt-plate w/ U.S. stamp, and cupped, 3-piece cleaning rod.

The stock is deep reddish-brown with some dents and nicks, but showing no signs of an inspector cartouche or circle P below the trigger guard. The forearm measures 4” from the muzzle to the back of the barrel band (and 3.5” to the front of the band). It has a fairly significant coat of varnish overall and no stamps or marks visible inside (with the action removed). Also has extremely precise arsenal inlets with the sling bar and ring.

The barrel has the usual “VP”, “eagle”, "P" stamps, along with an “A” approximately .5” in front of the barrel-receiver joint on the top. The receiver has the above-mentioned serial number, the breach block has the low arch and is marked: “U.S. Model 1873”. The bottom of the receiver (when removed from the stock) has an “X” stamped midway from front to back. The right side of the receiver/barrel/stock corner has the line-up horizontal registration lines, and the same position on the left side has a small “R” stamp (on my 1884 rifle, this small stamp is above the barrel/receiver reg. lines on the right).

The lock plate is a standard, undated version with the “U.S. Springfield” eagle stamp and is flush/inlet into the stock (no bevel). The trigger assembly has one small stamp on the inside/rear tang (“H”), has the pre-1883 smooth trigger, and the correct carbine guard. This carbine has the 1879 “buck horn” rear sight, marked from 1 to 8 on the left side of the base and 1 to 15 gradients on the sight ladder. Both the base and ladder are marked with the “C” carbine stamp.

Overall, this TD is in excellent condition, all parts (including sights) retaining approximately 90 to 95% bluing finish on all parts (with the exception of the last 3 to 4 inches of the muzzle that has seen some wear and is a mix of bluing and plumb brown. A good amount of case colors are retained on the breach block. I suspect that this carbine went through an arsenal over-haul at some point in it’s life, but because of its serial number (late 1887) I am having a hard time trying to figure out why it retains some late 1873 parts instead of the usual Buffington rear sight, serrated trigger, and Model 1884 stamp on the breach block.

Any help that anyone can provide is greatly appreciated.
