Help with ID on old Stevens break barrel

Hey everyone just looking for help identifying an old shotgun. It is a break barrel single shot .410.
All I've found is the same Steven's model under different branding. It is equivalent to a Worthington CHALLENGER or Crescent Victor. However, both of these models have the manufacturer specific engraving. The gun in my possession is simply marked with a large US inside a lateral figure 8 or "infinity" symbol. Any information anyone can offer would be greatly appreciated. Thank you.

It's stamped "US"? Is there a flaming bomb stamped on it as well?

Seen them in 12 ga but never 410.

I'd imagine without seeing pictures that it's a Stevens 107 if it looks like a Crescent.

No flaming bomb. I'll see if I can get on the computer this evening and get you a picture. In the meantime I'll check out the Stevens 107. I searched for a few hours and never found the exact model with markings.

This is a 107:
