That is --really-- sweet! And you didn't even have to replace the rings, how uncommon is that?
I think its pretty early for a Fray ratchet brace. The super open head and oversized chuck collar both look early to me.
If you keep it stored in ideal conditions you will get some mileage from the finish you made, but since the plating is essentially gone, it will darken.
I have blued a few braces and with a decent blue job, well oiled, they don't look or feel too bad in the hand at all.

Yeah Rusty, I suspect you know who was talking about casting pewter rings. It was what got me started casting pewter into tool handles of many kinds. :)
