I've read a number of posts regarding the 32 winchester ctg. My mother has one her grandfather gave her. The serial number is 14273. Given that info, can you tell me when it manufactured and if it is the equivalent of the .32-20 that has been discussed in this forum. I have looked the pistol over and have not found where it is stamped with M&P anywhere, even though many posts allude to that designation on many of the 32 winchester ctg's. Any help you can provide would be greatly appreciated.
