Thanks for the input.It's a little rusty and I can't find a maker mark anywhere.
Surprised that they are that common ,that two more are known. I guess just because I never saw one , doesn't make it rare.
I'll research the Blackhawk number and pass it on to the new owner.Someone decided
he needed it, and I just picked it up as a curiosty.
I have a couple of other spinner lug wrenhs , but they are one size sockets.
