15GP22 socket

[dtvmcdonald]

Steve McVoy has sold me a NOS socket. I will report on what I do after it arrives.

As to cutting a slot and unscrewing ... that won't work for two reasons:
1) they are too small and thus a slot will leave them with no strength

2) to cut a slot, one can't use a Dreml tool or the like, as it will
just slide off. One would need a quality machine too and a jig
to hold the socket
