hoping to get some information on an M1 Carbine. I am mainly looking for when these guns were manufactured. There are a few of these guns. The first is an Inland M1-A1 serial # 192510. The second is an Inland M1 serial number 6431818. The third is called a Quality Hardware M1 Carbine and the serial # is 4645551. I would appreciate any information I could get. We do not know anything about these guns but we have this information about them. Thank you
