John H. Krider, his rifles, and rifle-muskets are described on p. 386-395 of "American Military Shoulder Arms, Volume III" by George Moller. He states that Krider is believed to have sold weapons and accoutrements to Philadelphia area militias, including rifles in two different barrel lengths during the Civil War. The shorter rifles are noted with 33 inch barrels. This Krider short rifle is photographed on p. 391, and Moller wrote, "The narrow brass barrel bands used by Krider on these rifles are similar to those used on some of the military rifles made by Henry, suggesting these makers procured them from the same source. Also the brass implement compartment covers are similar to those used by another Philadelphia gun-maker, Christian Sharps, in his military arms. These brass implement compartment covers were also used as components of the 1861-1862-period military rifles made by J. Henry & Son and Phillip S. Justice." A "GDM" collection mark is at the toe. Includes a leather sling. Provenance: The George Moller Collection
