Trapdoor Springfields
McShooty noted that Trapdoors might be a nice rifle to collect and I agree whole heartedly.
While they may not meet the ATF definition of "antique," they meet the generally accepted definition well.
There is quite a spread of models with many used on the Frontier by the US Army and also in the Spanish-American War of 1898.
Often attributed to Erskin Allen, the master armorer at Springfield Armory, they were originally intended to use the surplus Civil War US Rifle Musket of 1963 as the basis in reequiping the US Military with a breach loader.
There are carbines, cadet rifles and infantry rifles and to collect all would be quite an achievement.
Basic rifle models are:
First Model conversion: 58 Rimfire
Second Model conversion: 50/70
1868: 50/70
1870: 50/70
1873: 45/70
1873 with 1879 modifications: 45/70
1884: 45/70
1888 Ramrod Bayonet: 45/70
Carbine and cadet model numbers generally mirrored the rifle nomenclatures, but not always.
There were also match Trapdoors made and many of these were awarded as prizes to top scoring soldiers in army rifle matches.
The Officer's Model Trapdoor is the holy grail for Trapdoor collectors. They were made to order for soldiers desiring a rifle between the cavalry carbine and the infantry rifle. Many have wrist mounted peep sights. Harrington and Richardson made a run of replica Officer Model Trapdoors for their 100th anniversary in 1970. The H&Rs now often bring high prices and are wonderful shooters. Reloading for them is not as dificult as for the original rifles with their three groove barrels.
With a good bore, a Trapdoor is wonderfully accurate and several of the above will hold two to two and a half MOA with well cast bullets, compressed load of black powder and the Federal 215 magnum primer in WW cases.
They are an absolute hoot to shoot out in the high desert and sage country of Western Colorado or Wyoming and shots at ant hills or prairie dog mounds many hundreds of yards away are not overly dificult once the range is known. A hit on one during the dry summer will bring a big cloud of dust and confirmation that your range estimations and wind call was on.
The 1879 sight and the Buffington sight of 1884 had the ability for adjust for wind. The Buffington sight is a marvel of ingenuity and accuracy and was no doubt the basis for the sight on the 1903 Springfield rifle of WW I and early WW II.
