I don't think it's U.S. maybe European? I'm not very familiar with the foreign copy's of the m1, but I'm pretty sure the U.S never used a plastic liner. 

Restoring a 1943 M5A1 stuart that looks like it ate either a pak38 or pak40. It was repaired and sent back out.  Im trying to figure out the history of the vehicle.  Serial number is 4169 and it was built in March 43 at the South Gate plant in calf.       Best i can figure is the round hit the headlight guard on the way in and that would account for the splatter / spall marks on the front armor plates.  They all radiate from one point which rays back to the headlight guard.  The undamaged area would of been protected by the lower slat of the guard.  It most likely absorbed enough of the kenetic energy to allow the area between the upper and lower spalling damage to not be marked or pitted.       Would love to find out the history, if the driver survived  etc.       Going to leave the damage from the shell l, would like to know its story. 

Nice patch by the way!   -Ski

Also I remembered when I was trying to research this I found two others also marked the same for sale, I don't remember seeing any with a different date.

I would like to know what this liner was made for. Is it related to the UN troops in Korea? The chin strap is getting brittle. The circle marking is the only one I can find. I have not seen ww2 to Korea liners made of plastic before. All the ones I have seen are lamination fiberglass.

I was recently playing with Google AI and asked about this canteen for kicks. I got to say, it has been my experience that this AI likes to give me the results it think I would like to hear.    Ais argument is this is likely belonged to a member of the 9th cav. It's logic is that the 17 inf co k was wrapping up their tour in the Philippines at same time the 9 cav troop k were starting their tour at the same duty location. It also mentioned that the hand written name and unit were more likely to be done by the 9 th cav instead of the 9th inf stating the 9th inf usually marked their names with proper stencils and although they had just returned from China to the Philippines, they were not stationed in the same part of the country. They also made a case the name was likely of spanish surname and likely a Philippines scout. There was member of this 9th cav with this last name.    This said, who knows if 9th cav or inf but fun to ponder. 

I found this old topic https://www.usmilitariaforum.com/forums/index.php?/topic/197578-officers-mess-kits-parts-to-trade/  the tray in here still seems a bit more round then mine.

So they weren’t issued?
