M1 Carbine Trigger Identification ?

[imntxs554]

I been looking in a couple of Books, but I guess I'm missing it. It's Mark looks like SKF or B at the end. I put it next to a NPM Trigger to see size and feature differences. The Trigger Pull looks like it has been Polished, but its not. Just a very Nice Shine and the edges are rounded. In the condition its in and right in front of you it seems to have been used a very long time or it's a very early Trigger. TIA.
