For fun, look at the underside of the extractor star, you will need to push it out as if you are ejecting the shells and look under, use a flash light as the numbers are small (if there, you will probably not see the K, just the serial numbers), QUOTE

SmithNut: Yep, the serial number is stamped on the underside of the star extractor, just as you predicted! You answered my question regarding the model name (Masterpiece) being absent on my revolver but I'm still wondering if it's common for the model number not being on the gun. As I mentioned in my previous post, my Model 14 does not have the model number (14) anywhere on the gun. Thanks.
