this just popped up on Practical Machinists https://www.practicalmachinist.com/vb/machinery-for-sale-or-wanted/sheldon-lathe-lot-tooling-363163/
While you are technically correct. Find one for a sheldon, Ill hold my breath.any lathe can cut metric threads, just need to figure out the gearing, usually a 127tooth gear is required.
Those small sheldons are good machines.
