The second group of arms (about 10,000) were produced between October 1871, and June 1872. These arms have their rear sight about 1/2" from the receiver and feature a double shouldered ramrod. All Model 1870 arms from the second production run have breech blocks which are designated "Model 1870" and have a long and high arch on the underside. Rifles from the first production run of 1,000 have breech blocks which are thick at the hinge, missing the word "Model" in the stamping and have the shorter arch like the Model 1868.
All Model 1870 rifles have a thumb piece which is rounded on the back corner.
All Model 1870 carbines have breech blocks that are thinned at the hinge and have high and long arches on the underside. The first 341 carbine breech blocks are not stamped with the word "Model." However, the last 20 produced have the word "Model" on the breech block. Carbines and rifles are chambered for the .50-70-450 cartridge. The front sight of the carbine is brass and held with a pin to the base. The carbine stocks were made new and only have one cartouche,"ESA." The firing proof is a script "L" in a small rectangle at the base of the trigger guard plate. Model 1870 carbines were not serial numbered. Possibly a set of numbers on the underside near the barrel/receiver interface may exist. To see them will require removing the action from the stock. The two identical numbers are stamped along the junction.
