Found a few items in a mechanics estate sale.  One hex (Allen type) driver I thought was 1/4 inch drive, turned out to be a 6 point female drive.
Does anyone know if a !/4 in square female to the male hex drive adaptor is made by anyone? 

My 1/4 in drive set keeps growing, and I use it a lot.  I even have some 9/32 drive sockets I use with an adaptor.

Part 2

Have Plomb Pebble wrenches increased in value the last couple of years?  It seems that people want at least 50% more than when I started collecting in 2016.  (Still missing a 3/8 (1212) pebble combination, that must be a unicorn)

If you find that 1212, please send it to me.  There's a big hole in my set just where it belongs....

For part 1, I need to see a picture to visualize it.
For part 2, I found my 3/8" combo in the wild in 2019. I was very surprised to see it at the flea.

For part 1, see if you can find an Apex distributor. Apex made/makes all kinds of stuff like that. Found a link.
