Post Reply - Milled rear sights with C or CH on bottom

There is a contract for "Carbine Sight Bases" that was awarded during January 1945 and final delivery was in March 1945

This is about a year after the adjustable rear sights were adopted. 

We know ordnance was pushing to update the rear sights in the field and there are several articles by Don Hillhouse of the earliest reporting of field upgrades. These were in the newsletters and more findings published below.

 

We know Hemphill was making milled adjustable rear sights for Inland marked H.I.  and Winchester H in shield. 

 

Packard was making milled rear adjustable sights marked PI

Springfield Armory made, or contracted adjustable milled rear sights, but unclear when. 

Some Hemphill and SA sights have been reported with a C or CH on the bottom of the rear sight.

We are asking everyone to check their milled adjustable rear sights and report the bottom marking as well as any manufacturers marks on the left or right side

If you turn a carbine upside down you should be able to see the marking with over head lighting. A flashlight may be easier

If you sight is on a late carbine and appears original, please share the serial number as well.
