They are addictive, beware, you have been warned. These are three of only eight I have. All three are Replica Arms, Marietta, Ohio, ser. nos. 10 (38 Special), 222 (45 Colt) and 273 (357 Magnum). All three have the original style Remington Cylinder pin retaining spring. Not sure how many were made like this before the change over to the cross pin like the later Colt's, but by the 1200 range they were definitely cross pin. Also have never seen a Replica Arms gun in 44-40, tho there may exist some. Earliest 44-40s I've seen were marked as Navy Arms.
