John,
I just realized what I thought was a mounting screw is also the focus screw. My sockets appear to be newer. I saw in Brattons catalog the sockets description says " foreign and fair quality". Mine look like thes with pig tails. Turning the focus screw spins the whole socket. Am I missing a part? If foreign and fair are the new part options I'm not sure what to do next. Any suggestions welcomed.
