I can't quite make out what it is. It doesn't say trigger guard to me though at first glance. Put it against a dark background and it will photograph clearer. White is about the worse thing you can use as a background. I'll try again, OK? Monty.
That's better! I can see how it resembles a trigger guard, but it just looks like something is not right about it. May be , but I really can't say one way or the other. Sorry. Monty
The curves are a little unique and reminded me of a tg to an old savage like this one. But even for a broken tg, the hole isn't right and I'm with Monty that's something's peculiar. But it does look like a trigger guard to me.
