Gas Trap receivers with 44 barrels/stocks?

I just went and looked at notes quickly for a Garand I have. Its five digit/w 44 barrel, saw cut gas cylinder. #20555 or something like that.
Nothing extra ordinary I can tell from it other than it has the concentric ring trigger guard and it runs like oiled glass when its in use.

I received it from the CMp a few years ago. Rack or Field grade it was,and when I ordered it I requested a new barrel at the same time which went on something else.
Luckily for me, I didn't need to replace it .
So, I replaced the op rod spring, went over it, shot it a few times and was surprised at how accurate it was with ball ammo.
Very surprised actually, but maybe that days outing was just a fluke I'm no tournament marksman to say the least.

I can now recall it has a Winchester bolt, the ejector was near frozen etc. I greased it up put it away and haven't had it out since.

Happy Thanksgiving all - Blessed Holiday season, pleased to be able to contribute a small bit here,
