Confusion exists related to the Crescent 'Hunter' sidelock made for Belknap Hdw. and a 'Fulton Arms Company' by the W.H. Davenport.
Hunter Arms made a number of tradename guns using the Fulton 1918-1919 (including a Gladiator for Sears), and later the Ranger for Sears. Dr Jim and I are submitting an article to DGJ about the tradename Fultons.
In reviewing the Hunter Arms shipping records and the 1904 Annual Report, Dr Jim also discovered that the Hunter Arms boxlock 'Hunter' was first made in 1904, but not patented until 1911. The name was changed to the 'Fulton' in 1915. No boxlock Hunter guns are known to exist.
