Got these 5 pair of pliers in a box today. 4 pair have screwdriver handle tip and one of them is scrip Ford but the right hand pair does not have a screwdriver tip and mark is unknown to me . Looks like a (R) ina circle. Have ruled our Moore and Bonney. Any help in identity appreciated. Did John Deere use any plier other than the Mossberg that Dill lists ? One pair shows what looks to be original green paint. Sorry about the fuzzy close-up of mark;thats the best of 3 attempts. I take photos just slightly better than I speak mandarin.

Not that it helps you at all but that looks like it could also be a H in a circle, at least in your mandarin picture it does.

 Top of mark appears  to bt closed using my magnifier

I am leaning heavily towards it being an H also.
AA lists the (H) logo twice, once under Craftsman, and once under New Britain with a comment 'also used for Craftsman', I take this to mean NB sometimes used it on non-craftsman stuff, which would make sense if they had stuff left over....

 I'm going to have to go with the H as well since no R markings are known. Looks like top of letter is filled in but probably a bad strike . New Britain it will be until proven otherwise.
