Had a good visit to a local antique shop this afternoon. In addition to a couple other nice items, I got a set of bits. They look just like the bit on a handled gimlet but, they're made for a brace an are sized 6,7, and 8. Made by Snell mtg co. So, is that what I have, gimlet bits? Also, a bit shaped like a tapered birdcage awl.. Again for a brace. Thoughts?
