Saddle thread/bolt size

[Manual Mac]

The parts list shows it as a 7/16" x 14 x 1-1/4" for my lathe. But @mmcmdl is correct in that more info is required. Like size, model, year, etc.

Both my SB9’s (‘36 & ‘38 workshop type, not junior type) have the machined boss’s, but not drilled & threaded (for the taper attatchment?).
Both would be called C models now, but there was no A,B,or C designation yet as there was no gearbox or power cross slide available yet. I could be wrong, but I don’t think so.
Sorry about the lousy phone photo.
EDIT; just noticed this is reply #666 for me, hmmm…..
