MD- I've found the following trade names:
"A.J. Aubrey”, “The New Aubrey”, “Utica Special”, “Gibraltar”, “Challenge”, “Gladiator”, “Berkshire”, “Colton Firearms Co.”, and “Meriden.” This does not include the revolvers (some under “Howard Arms Co.”) and rifles.
There were also "Gladiator" guns that were both Field Grade Smiths and Fulton guns.
