I am brand new to the forum, and I'm glad I found you. I have long had an interest in the M1 carbine and I'm looking at one now to buy. I need some assistance with the markings and possibly a rough estimate on value. It is a National Postal Meter, serial # 146XXXX, with Underwood 12-42 stamped on the barrel. It has the CAI Georgia Vt. stamp on the underside of the barrel. The same serial # as on the barrel is imprinted into the left side of the stock. On the right side of the stock is the GHD over UEF with crossed cannons within a rectangle. The barrel band has "K I" stamped on it. There is no bayonet lug. Inside the slot in the left side of the stock appears to be the letter S, then 2 letters I can't make out, then a letter U. There are numerous dings in the stock, but it is not split anywhere. As I said, I'm completely new to this, and want have more knowledge about this M1. Thanks in advance.
