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
