So this is probably going to be of interest for only real P&C history buffs / geeks but here goes...Years ago, John Derville Jr. relayed to me the story of when Ned Boyd sold his stake of the P&C retail arm to his father John Derville Sr. who was the Asst. Mgr at the time,and left P&C in the late 20's with Sherm Haskins and tool and die maker Pete Mortensen and started Thorsen Tools down by the Bay. ( This ended up on AA and apparently there's a similar condensed version in the Shurtleff family history) So yesterday I was mega bored and made a very half a$$ed attempt to run down whatever happened to some of the guys and I came upon a patent and apparently Pete ran into Howard Fowler in Oakland and co-patented some fluid/air pressure etc.coupling device ideas. The name Fowler sounded familiar and I did a quick search and came up with this air nozzle and also a radiator water nozzle both of which I have in my garage tools on the west coast....Anyway.....I started looking at the Company name and it hit me (possibly) that the PEM in Fowler-PEM Co. is Peter E. Mortensen. ( E. IS his middle initial.)...watcha think?
Edit. so i looked a little more and found, among others, a 1966 patent 3,267,553 to a Peter E. Mortensen assigned to The PEM company...at this point located in Milwaukie Oregon.
Here's some of the earlier Patents Mortensen had some hand in 2,044,252 2,074,021 2,091,515

Nice detective work. Seems like a plausible explanation.
Good Sleuthing! That sounds very plausible to me... I think you should write a book or paper on your research not just on subject but on p&c/general tool/thorsen....there is so much mis information out there but I think you have the best shot at connecting the dots correctly for everyone.![]()

I’m generally against restoring old tools, but that thing would look awesome repainted and polished! Is it aluminum?
Nifty yes, but finding P&C electrical wrenches is not very nifty at all.I don't recall ever seeing a board designed to hold DOE wrenches like those electricals at the bottom. Kind of nifty.

I got your 2818 and 2810. Pm incoming.
Thanks guys!

Excellent! Replied and THANK YOU!
Hey username, What does the back of that board look like? I have a couple of versions but have never thought they might be for table top use.
Here's a shot of the back side. Looks like original hardware. It collapses down so that it can be hung on a wall or unfold the leg to set it up on a countertop.
