The Boxer and Cambell Co. Detroit Mich. pliers

[oldgoaly]

Well it might look like I collect these but they are from piles of stuff from auctions and swap meets. Didn't turn up any thing on a search. they are pressed steel not forged about 12" long  with file like serrations on the business end. Any ideas on what these were used for?

"Boyer and Campbell" were tool and machinery dealers, so probably an advertising piece, or their house brand of someone else's pliers...

(Can not find a good ad, most hint is 'tools for fabricating from metal and wood....)
