Canvas Parts Markings 1 

Cover, Canvas, Muzzle,
Rifle or Carbine
Used with the M1 Carbine, M1 Rifle, 03series rifles, shotguns, B.A.R.,  Thompson SMG, and any other small arms. It was used to cover the muzzle and keep dirt and foreign objects out the barrel. There are two snap locations to suit different weapons.

The earliest reference I have found so far for the "Cover, canvas, muzzle, rifle or carbine" is in Quartermaster Depot Units, Aviation book for the Quartermaster School at Camp Lee , VA in late 1943.
"This publication has not been officially approved by the War Department. It has been prepared and is issued for instructional purposes only."

What is interesting is that in earlier weapons manuals it states that "the use of canvas or similar covers are prohibited, as they collect moisture and rust the metal."
This is referring to storage, which is not the purpose of the muzzle covers.
It has been reported from members that storing a carbine with the muzzle cover will promote rusting of the barrel.

Below are the 38 variations that have been reported thus far, 7 of which we do not have pictures of and are looking for submissions. It is very possible there are other variations or dates. Please let us know if you have something not on the list

The covers were replaced with cellulose tape in 1944, Yet we see 1945 dated covers on the list.
This form of tape was actually in use and formally called nonhygroscopic tape and used for sealing apertures in materiel.

Here's some photos which came from an original package sold on ebay at some point in the past.

Box with instructions

Roll of tape

The tape above, as can be seen is Stock number 53-T-1085 Taper, cellulose, muzzle cover, 100 ft. per roll. 
As late as 1954, and probably later,  The tape is listed in "Quartermaster Substitute and Interchangeable Items" with the substitute being stock number 74-C-306 Cover, Canvas, muzzle, carbine or rifle. So though the tape replaced the covers, they were still in use.
The question here is if the covers were using that stock number in the WW2 time period?

Slingo submitted a better picture of the Kanak 1943 with the hash markings (added above)
Also another Kanak 1943 without hash marks. The U.S. and spacing is different than the 1943 and 1944 versions as shown above.

Thanks to Dan's keen eye, the 1943s have a printed line on the US side at the strap.  The 1944 (on the right) has no line, it's a shadow.  The no hash 1943 has the shorter line.  Looks to me they may be location/match marks for attaching the strap?  As shown in the bottom pic, the 1944 not having this line is sewn farther away from the seam.  I guess it was more "skill of the craft" and save ink?  Also the strap stitching on the 1943s is a running (?) stitch box with X.  The 1944 has just 2 parallel full width embroidery (?) type stitches.

A few guys reached out and bought a bunch from the LR collection. Last night I listed most of the rest on ebay. Check out Ruthintheoutfield if you are looking for any specific ones." rel="nofollow -

As far as the canvas getting moist I wonder if anybody ever put linseed oil on the canvas to make it more durable like they did to Canvas sales on ships
