Mack Truck Pliers - Who made them?

Does the pattern on the handle give indication of what manufacturer made these pliers?

Look like Crescents to me.

That is it!  I thought it looked familiar - I should have gone out to the garage where I might have had a Crescent or CeeTee pliers.  Thank you very much geneg.

I think the same pattern on a pair of Cee Tee ones as well as these Motorkits.  I have a box of various brands of these 5-1/2 inch pliers in my office.  I've procrastinated sending them in to the under 6" tool section.  I'll have to get it done someday.
