The grouping includes six documents total, all of which pertain to the Colt Patent Firearms Manufacturing Company. The first letter, dated 9 August 1859, is from the Chief of the Bureau of Ordnance and Hydrography (U.S. Navy), and is a request for 100 of Colt's rifles to be sent to the Washington navy yard that are "similar in all respects to the one recently tested by a Board of Officers at that yard." This letter is addressed to Col. Samuel Colt, and is undoubtedly a reference to the Model 1855 revolving rifle. Two of the letters, dated 1874 and 1876, are correspondence on Colt letterhead with Adams Nickel Plating & Mfg. Co. of South Windham, Connecticut, that appear to pertain to the outsourcing of nickel plating firearms parts by Colt. Another document appears to be a brief note on shipping. Another letter on Colt letterhead, dated 12 October 1861, is addressed to James Savage Esq. of the U.S. Commissary Department, and is a reply to a note by him that appears to be requesting Colt rifles that can accept a bayonet, which may be the Model 1861 Special rifle-musket produced by the company. Also included is a Colt advertisement pamphlet from around the same period as the other documents, which is printed on blue paper.
