WW2 Carbine Late Features

[firstflabn]

Here are the rear sight field upgrade instructions, which could have been happening in theater, April 1945.

ORD B28-W3 was issued in March 1945.

"Could" is a bit of an understatement. By the spring of '45, parts or all of 15 ETO divisions had had their carbine rear sights replaced per MWO ORD B28-W3.

This MWO was published in Sep 44 (not Mar 45).
