Hi 3Bay,
I just couldn't resist the Whitworth. I have seen another but it's in England! It can stay there I think.
Lineman's ratchet - is the handle insulated from possible electric current passing into the hand of the operator? If so, one hopes he (or she, it is 2020 after all) doesn't change direction of the ratchet mechanism while it is on a live bolt! That ratchet direction changer is a neat addition, for gloved hands I expect. I have never seen anything like it before.
I have only seen one or two "Specail" marked tools, may well have to get one just so I can say I have one ... that's how it starts I guess.
I have seen on another thread a photo of a member's three offset boxes like mine with just a diamond W and no oval or round shank ... pretty plain which made the other member wonder, as I did, if that method of production was for some low cost variety made for some other distributor. William's low cost short offset boxes I have seen, and I have one, look just like regular JHW tools.
One responder to the other member's posting was to suggest a military contract. I take it that you might be suggesting a special factory contract with, say an auto manufacturer for use on an assembly line?
Mystery can be fun.
