Maker's mark on old USA Tap wrench?

Found this in my dad's stash. Seems like a good one. Who's the maker?

Cool, thank you. Seems like a good one but bigger than I'll probably ever need. I do need decent smaller ones though so maybe I'll try to get matching ones in smaller sizes.

We're there different lines being made at the same time? What line is mine?

At one point they changed the numbers, with only the #7 staying the same I think.
