Years ago I glommed a couple of M1 carbines from the CMP. One was an Inland and the other was an Underwood. Over the years I've shot them, but never really gave them a good going over as to which maker made which part.

Recently, a forum member on another forum posted his new Underwood carbine and noted that the receiver had been subcontracted out to Universal Windings. That Underwood had contracted out some of its receivers was news to me and inspired me to look my Underwood over a little more closely.

Sure enough...it, too, has a Universal Windings receiver
