I have a Colt Detective Special in 38 Special. It's in approximately 98% condition and has the box and original paperwork. It also comes with a leather holster marked "Evaluators, Quantico VA, FBI Quick Draw". The 2" barrel is marked "DETECTIVE SPEC. .38 Special CTG." The serial number is 563220. Even the checkering on the grips is nice and crisp. Any ideas on it's value? Thanks.
