Need part numbers for a 9A steady rest

[Jim in Wisconsin]

Mine looks just like Manual Mac's with similar numbers, except instead of "SP" mine looks like "BP" or maybe "8P". Those figures are cast in and not very clear.
I don't have the roller fingers, Mac - do you know where you got them?

I can’t remember where I got the fingers with the rollers, but they’re available on EBay or Amazon for $20 or $25 I think.
