Need help to identify some buttplates?

Need help to identify some buttplates?

I recently saw 2 or 3 investment cast buttplates that had an "H" on the inside.  One of them had an H in a circle cast in.  One or 2 had a large "H" cast or die punched in.  Very nice and very clean castings.

Any info on who made these would be appreciated.

Thanks!

That could be a Jim Chambers casting and if it is that would be a JC and not an H
