Default Trigger Markings

I recently stripped down a SA -12 trigger housing to replace it with a correct IHC housing.

When I pulled out the trigger, I found a marking that appears to be a large "8". I can't find any reference to markings like this in my books or on USRifleCAL30M1.

I assume it's a forge number? Is it SA? Or IHC?

Thanks for your help.

SA war time forge numbers, also found on bullet guides, follower arms and I have a gas cylinder with a partial one.

You'll never know, it's a forging mark and meaningless.

I don't think post war parts have forging marks. So not IHC or HRA. I could be wrong but I don't seem to see them.

Page 774 of Canfields the M1 Garand Rifle book "Some triggers chiefly SA will be found with a raised letter (S) and sometimes a number adjacent. These were formed during the forging process and were reportedly intended to identify the die used in the procedure. Typically these raised markings were removed during final machining but, on occasion they were not totally obscured."

I guess that nails it! I just ordered Canfields books on Amazon. I obviously need them.

Thanks for that!

I don't agree with it either Bill. I have just seen too many triggers, bullet guides, and follower arms with these forging numbers to believe they were just an occasional ocurance.

+1. Pure speculation on his part IMHO.
