For your Craigslist consideration today here's a vintage Snap-on 3/8" drive ratchet for $20 cash FOB Pomeroy WA.
Ratchets as designed, both clockwise and anti-clockwise.
Selector functions as designed, switching between clockwise and anti-clockwise.
Socket retention detent ball has appropriate spring pressure.
Owner's marks and finish wear noted. Probably could stand to be opened up, cleaned, and lubed as well.
I do wander over to the L/C area from time to time and could bring it along if that helps.
