there are (basically) two types of trapdoors. The rifle and the carbine. (There is also a cadet model) The rifle barrel is 32 5/8" long and the carbine barrel is 22" long. Since you say 'short forearm' it would appear you have a carbine. Measure the barrel to be sure. As to value, it would depend on overall condition, finish, serial number (when it was made) bore and wood...................send me the full serial number and I will tell you when it was made.
You need to tell us what model of what firearm. Auto Ordnance made a .45 cal semiauto carbine and a 1911A1 pistol.
