Granville for one.

I think the older Warco BH600 type also have 20DP gears.

Holbrook Model B Number 8, I think Zyto and other Myford style copies

[Micky TParticipant @mickyt]

Grayson have the same gears as the Myford

Must be a very old BH600.

My 2003 ETR BL12/24 ( a BH600 / Chester Craftsman clone) uses metric changegears, 1.25 Mod from memory.

Probably my poor measurement on my (very old!) Warco 1327. 20DP converts to 1.27 MOD, so not too far out, but far enough!

I've used a Myford gear once I'd modified the keyway, and it didn't complain, but my original meshing gear is probably worn enough not to notice the difference.
