first petersen I've seen with this screw

Cool!  Does it look like an early one?

its a 7wr,eeasy release...ive bought and sold lots of vise grips,this is a first

Ok, that is first for me too! Wow! Neat!

Time to go through the Petersen Vise Grip drawer!! I have never seen that stamp before!!

Nice, logo looks good too. Never seen 1.

What is the emblem? - can't make out what it represents.  Cool, though, pretty sure I've never seen one.

Looks like 2 jaws gripping showing "griptation" in action.

looks like two hands,like shaking hands?

It is two hands shaking.  I checked and I have at least one with this feature.  I was really surprised to find it.  I still need to go through the rest.
