Wait. Why are we talking about Craftsman? There is no way that's a Craftsman tool without a Craftsman branding. As for it being an NB tool, that makes no sense to me. I can't think of any case where a Craftsman code was used as branding by the Sears supplier it was associated with outside of Sears/Craftsman. Craftsman codes, including Circle-H, are usually small, much smaller than branding, and placed adjacent and often subordinate to branding. The size and primary placement of this H in a circle clearly smacks of being its own logo or trademark. As for the mark itself, I'm pretty sure the H inside the circle of the Craftsman code, like all letters inside all other Craftsman codes, does not touch the circle. The arms and legs of the H in this marking, in contrast, intentionally merges, by design, with the circle.
My $.02, anyway. Which may be worth much less than that after my erroneous opinion of the grip pattern!
(I have a lowly opinion of Harrold, probably influenced by them growing on trees around here alongside their economy line 'MH monogram in a circle' McKaig-Hatch made brethren, I don't own a single pair, and I could've sworn the dozens I have left behind at flea markets were smooth handled. I was clearly wrong!)
With the grip pattern matching Harrold production, and that big H, isn't Occam's Razor screaming Harrold, despite its apparent rarity as a marking?
EDIT: Afterthought: Maybe not so odd given how many variants of markings they have. HARROLD in a circle, that triangular indent with the <-H-> marking (which seems to be a modification of the "<-H.J.H.->" marking they TM'ed), no branding, etc.
