Mark, I might have some, I'll have to check when I get home.
Remind me if you don't hear from me later.
Do you know if these are the ones that are cone shaped with splines and the outer ring has a bevel on the inside diameter like a number of 49-50 RCA's used?
They might look like the ones on a 2T51:
