Monarch 10EE with an IM gearbox and dual IM dials. While you're at it, make sure it has a 30" bed.
LOL! And greater swing .. but mine is branded "Cazeneuve"..
Seriously, UK, Nederlands, Belgium, France, Italy, Korea, Japan, and Germany ALL made one or more right-decent manual lathes with Inch/metric built-in.
Inch goods had been common in pre WWII Europe, the war brought more-yet in with occupation forces and their eventual surplus to Europe, Korea, Japan as well.
Europe for many decades had far the greater need to be able to work with
both than the US does, even yet today.
For all the penetration of metric goods in our domestic market, many are "disposable", never see a repair.
For the more durable, we have far more spare parts and threaded goods "ready made" in both systems than was common in earlier eras.
My greatest need for metric has been automotive-related for nearly sixty years. Italian, Japanese, or German cars first, then US and UK-made vehicles as well.
Whatever I needed has
always been a parts-bin item. No need to make one at all, either system.
"Thread restorer" files, both races, many pitches, were good enough, ELSE buy new.
Whom DOES need wide-range single-point threading?
Those who get involved with firearms, any age, or elderly 2-wheelers.
Both US and UK bikes and one or more fasteners on nearly ALL firearms - have used some of the rarest of fasteners out there, either system. Even so, if one can find a tap or die, "go for it".
If nothing else, the SIZE is usually right, so a PITA as to measuring threads accurately and well can usually be side-stepped for simpler tight/loose, go/no-go.
