Much to clean M1 Garand Trigger Group

[usabaker]

My friend's son text me this GunBroker auction for a Winchrester trigger group. When I saw it, I was like hmmm.. "shows almost no wear –most likely reparkerized to look this good "

He has been looking for a Winchester trigger group for his, its the only part in his Garand that isn't WRA. I told him I toss it up on this group to see what y'all thought about it. has an OUCH price tag as well.

Hard to tell for sure, has that been Ceracoated? Looks like that rather than Parkerizing...I don't think for a minute it's original finish though. I took a look at the pics on the site, still looks like Ceracoat to me. No way it's original.

Never seen the diagram parts numbers highlighted in white before either. If it is Cerakoted, you can have it removed and an original type finish applied. Sounds like Winchester trigger groups are few and far between.

Seller says... "WW2 -US Military - M1 Garand - Winchester Trigger Assembly/trigger group. D28290 W.R.A. WRA housing. WRA hammer. WRA trigger guard. WRA safety (WRA-1). WWII winged plunger . Complete working trigger housing assembly. Came from a properly working rifle- test fired good. Typical Winchester rough machining marks. Very nice even dark green finish shows almost no wear –most likely reparkerized to look this good - see pictures. Locking lugs are very good and lock up tight. Pad has been modified – see picture #5 . Should work in any USGI military M1 Garand but would be most correct in a WW2 Winchester. I added white highlighter to show up part numbers, white can easily be removed if buyer does not want it."

You might pay over $200 or even $250 for an original finish WRA trigger housing, of course top marked safety would be more. Most WRA WW2 trigger housings had the large pad, the one in the post has the cut down pad. Also CM and A marked parts will also increase the value of this part

This was helpful information. I will pass this on to him.

Thanks Bill

Most WRA WW2 trigger housings had the large pad,

Where is the pad? I'm nor seeing it :/ is it the one on the far left?
thanks Bill

The first few hundred SA trigger housings were manufactured without a pad, problems developed and a "hammer buffer" was introduced which is a large pad. After round top safety came into service, the large pad was reduced in size ( medium and small).

Photo shows a large pad Winchester and SA round top safety, sometimes the round top safety will not "snap in" the trigger hosing because of the close tolerances of the large pad.

I might suggest the finish is possibly a paint like alumahide, rather than cerekote. Notice the "hairs" that formed on the imperfections on the joint edges? I redid an old beat up Glenfield receiver and parts with alumahide. I've never done a cerekote job, but I would expect it wouldn't fill in all the tool marks like the finish in the photo seems to do. Paint, especially an epoxy paint like alumahide, does.

Listing says "Very nice even dark green finish shows almost no wear". It doesn't look dark green to me. Maybe someone that parks guns for living, like chuck, will chime in.
