For your Craigslist consideration today here's an antique brace wrench for $40 cash FOB Pomeroy WA.

The Lowentraut 20th Century Combination Tool; an oddity spanning the use as a bit brace and an adjustable wrench.
Missing an additional spinner handle; they do turn up from time to time, eBay and primitives antiques.
I do wander over to the L/C area from time to time and could bring it along if that helps.
Thanks for looking!
