Hey guys. new to TFL! I recently purchased a police trade in model 10 from buds. Its a 10-10 and i was wondering if anybody would be so kind as to date it for me?? The serial # is bht3xxx. Also ive herd of people being able to identify where (which P.D) there police trade in guns came from. Any idea how anyone? Mines got a sticker on it with vpa01xxx on it and there are numbers that looked post factory ingraved on the arm that the cylinder is mounted. Thanks guys happy shooting
