Well, I got this good news from Dema Elgin, one of the top in his field in the US:
The good news is that every one of your lifters was above 65Rc!!!! We reground them all today and can ship them back to you via UPS.

I had to do a Wiki lookup to find out what a 65 Rockwell score is:
Typical values
Very hard steel (e.g. chisels, quality knife blades): HRC 55–66
(Hardened High Speed Carbon and Tool Steels such as M2, W2, O1, and D2, as well as many of the newer powder metallurgy Stainless Steels such as S30V, 154CM, CPM-M4, ZDP-189, etc. )[12]
Axes: about HRC 45-55
Brass: HRB 55 (Low brass, UNS C24000, H01 Temper) to HRB 93 (Cartridge Brass, UNS C26000 (260 Brass), H10 Temper)[13]
I will still let the list members know how my search for new ones turn out; so far GBS has two. Colombo none (sounds like a sports score).
