Carbine Trigger Group Help

[Nubber]

I bought several trigger groups 15 or 20 years ago and just found them hiding in my parts room. This one has me stumped. I find no markings and it looks stamped and brazed. Any thoughts from the group?

Look at the top front of the magazine well and there should be a .U. there.

Thanks BrianQ, it was there, I just missed it. Would this be a early or late housing?

Not BrianQ, the the stamped / brazed Underwood housing is later use than the milled housing. There would of course be some overlap period.
