This being the photo below. Which shows a reverse spindle gear and reverse idler that clearly do not mesh. Both are square dial parts, but the reverse spindle gear is from a late 60's single sight glass machine of unknown progeny (parts sourced on Ebay), while the idler gear is a standard idler gear from a triple sight glass toolroom 10EE.

I'm not sure which pair you're calling reverse, I assume that they are EE-2110 and EE-1099? How many teeth on each gear?

The 1941 round-dial headstock drawing (EE-99) calls out the two clutch gears on the spindle as EE-2110 (60T-16P) and EE-2111 (60T-14P). They mate with idler EE-1099 (44T-16P) and EE-1094 (60T-14P), respectively. Curiously, the 1985 revision of the headstock sections drawing (202.268) calls out the clutch gears as EE-2110 (56T-16P) and EE-2111 (56T-14P) and the mating gears as EE-1099 (41T-16P) and EE-1094 (56T-14P). It seems very odd that the number of teeth on the gears would have changed without changing the part numbers! The 1944 square-dial headstock drawing (EE-4-35) has the same part numbers for the gears, but doesn't call out the number teeth.

Cal, you nailed it. You never know what you are getting on Ebay, The reverse gear is the one on the left. I have always identified it by the location of the oil line in the bushing. Evidently someone had disassembled the gears and reassembled with the parts mixed. So I had the 14P gear trying to mate with the 16P idler. All the gears are 56 tooth.
