Which style feedscrew does the M125 use? I don't think I've ever seen that model, does it have the manual crank? I think I may have an extra feedscrew/half nut that fits the M5-S style, a 210 OI, but it could be it's for an M5, I have to dig it out and check.

Pretty sure the -S suffix is for "spiralling", meaning it has the pressed brass gear on the outside end and the clockspring overrunning clutch near the inside end. The M12 and M5 (if the latter exists) without the S don't have these. Also the M12/M12S overheads only fit 13 1/4" blanks, so they're shorter than the M5S which fit 16" (nominally) and 17 1/4" (in a pinch) blanks.

If anyone has the 105 and 135 lpi OI screws/halfnuts for an M5S, or anything IO, I'd be interested. There also might have been 90 and 180 lpi screws available at some point but I can't confirm it. I seem to recall Rek-O-Kut was a subsidiary of a brass foundry company that may or may not still exist, and I've wondered if they ever had a back room with a bunch of dead stock.

The M5 exists, as I currently own one and previously owned another. However, the one I have now has the clutch and crank, the other one did not, so I wonder about the accuracy of rek-o-kut's labeling system. I also have one labeled B5 which is the same as an M5S, it has the crank and uses the larger feedscrews.

I do have a 120 IO feedscrew for a M5S, although I've never used it, and would have to verify that the halfnut is correct, but I don't think I'll ever have a need for it. So if you're interested in a 120 IO, let me know.
