Findings from Saturday's outing:
It's more sophisticated than it may first appear. The knob is flat on one side; the flat is tangent to the ratchet, so you can drill holes very close to a corner. The little widget off to one side is the ratchet control: pull it out, turn it 180 degrees, and the ratchet is reversed!
Here's the bit-holding recess, shaped to the receive the square frustrum of a typical brace bit. The clamp screw is stuck -- I hope to free it up but the drive works fine without it.
Tiny pipe wrench, just because.
Set of wood-screw countersink/starting hole drills, not antiques but useful and they were priced to sell.
Here's a telephone transmitter. Dimensions appear standard, design is of an older sort.
And a variometer! Nifty variable inductor.
I also picked up a dozen QST magazines from the late 40s/early 50s and a collection of the complete works of Edgar Allan Poe. Not a bad haul!
