Counterpart seems to be a huge wholesale company. Probably Chinese. No website when g o o g l e d. Classic parts does identify which are USA made and you can see the Newport logo on some.
Some 12V on Classic site are not labeled USA, so those would be the "off shore". As said, none of the 6V say USA made and Newport does not have a 6V unit. Newport mentions knob modification.

Some off shore stuff is good , some are not.
