Very nice, thanks for sharing! Ken 

Beautiful carbine! Being late or post war, is it marked M1 (hopefully) or M2?

Here are some items from the Western Cartridge Company.  My wife's grandmother worked in that plant during WW II.  They made small arms ammunition (.45 ACP and shotgun amongst other calibers).  

Gotcha man thanks for the input!

The US made period M1944 nets always have stiff bands, I have 4 of them and 3 loose WWII neoprene bands, they are all stiff and hard to stretch. The post war M1944 style nets seem to always have very elastic bands, the nets themselves are usually much softer as well and usually a pea color green, while US M1944 nets are very dull almost grayish green.    Nice net!

You're welcome.  Here is a few more related items
