57/64 Spark Plug Socket, mint condition

[brad54]

I'm helping a widow clear out her husband's things (he was a car guy), and came across a 57/64 socket; 1/2-inch drive, 12-point deep, made by Herbrand. The Alloy Artifacts website puts the manufacturing date as 1944/45. It's in fantastic condition: on a scale of 1-10, it's a 9.

The odd size fits early spark plugs.

I'd like to get $20 plus shipping for the ol' bird.

If you've got the early plugs, you know how hard it is to find this odd size... it wouldn't hurt to have a spare!
