I'm not sure just what you have. There have been a dozen or more firearms manufacturers named "American" something and several other made models named "American" something. The only model I can find listed as "Action" is a cheap Spanish 6.35 automatic. If it is a 38 caliber, the 1850 must be a model number as there was no such thing as a .38 cartridge in that year. If you can repost with everything that is written on the gun and describe any symbols or other markings, I may be able to help you. Also, tell me what type of gun it is. I'm assuming a revolver, but a .38 could be an automatic pistol, derringer type pistol, or a rifle.
