I have a large Indestro socket, it's a similar style to yours, when I'm at my shop on Sunday, I'll check the size, whether it's a 3/4" or 1/2" drive and what condition it's in.
Frank,I have very nice 6432 1" has not been cleaned.looks to be the same quality as yours,has a few tool box dings.I need some 3/8"dr. metric ;;12,11,10 in 12pt.
The one I was thinking it was is actually a large Williams (with 3 rings instead of the 2 the Indestro's have). Something tells me I might have an Indestro in my "extras box". If I find one in there I'll let you know. Sorry.
