My condolences. I naively assumed the front mount selector knobs were a more convenient means of selecting the full range like Norton-like gear changer, more like @John Conroy GH 1440 lathe. I guess not the end of the world but something to be aware of. The Colchester is a Beast!Correct. and the stuff I thread most (3/8-16, 5/16-18, 1/2-13) are all different gears.
