Default Milled trigger guard with S

https://imgur.com/a/z3xiG03

Not sure this is really an S, if itís desirable or rare. Looked it up in the Canfield big book, no mention of an S mark. No drawing mark on the bottom.

Any expert opinions?

That is not an inspectors mark. That is a forging mark to identify the forging die used for that particular part. That area with the letter is usually removed during the milling process.

I have seen similar marks on a couple of triggers I have and I wondered about that. They do appear to be milled but not to the point it is gone.

Trigger guards are not cast. They are forged.

They are forging codes. You will also see them on bullet guides and follower arms. I believe there are illustrations or descriptions of this in Duff's Red Book.

Often seen on bullet guides, follower arms, triggers. I have a gas cylinder that still has a partial. I have seen it on trigger guards as well. I think it is pretty cool to find these on parts. Wartime manufacture.

Good Day! Iím a bit confused. I have two trigger guards with letters/numbers on the side and one of them has an inspection mark inside.

1. Has what looks like an S on the edge of the guard and it has a ĎJí inside.
2. Has what looks like an S5 on the edge of the guard and no mark inside.

These marks on the edges are just casting marks?

I would say the "J" is an inspection mark. I've read about them but don't have any on mine.

The J is an inspectors mark. The other marks are forging marks from the forging dies. They are not casting marks because the trigger guards are not cast, they are forged.
