Monday Mystery, Gerd Paul's 50 year Knife
I found this knife in our cutlery drawer, apparently inherited from my wife's grandmother. The engraving is a phrase, "Gerd Paul's 50 year knife". We use it as a pie server and indeed on the back there are arrows pointing to a serving function, slice and cut. I can't find anything online regarding the name Gerd Paul or reference to a knife.

Bowden cables
In 1879 E.M. Bowden applied for patent 14,402 for "the use of a flexible inextensible wire inside an flexible inextensible tube". It's first use was for bicycle brake actuation. Before this all mechanical linkages were variations of rod and lever assemblies. Nearly 140 years later, the invention is as relevant as it ever was.
The company's foray into carburetion in the 1920s was less successful, though the logo seems to be inspired by (copied from) Triumph!

P&C Clik-Stop
P & C Tools was a trademark registered to Plomb and later Proto tools of Chicago. The initials are from the founders John N. Peterson and Charles F. Carlborg, who started the company in Boise Idaho in the early twenties. The whole story is here at Alloy-Artifacts. I haven't been able to find what the Clik-Stop refers to or if it ever actually had a patent issued.

Fairchild Flying Boxcar
Unfortunately we have none in Canada though the RCAF operated 35 of them from 1953 till 1967.
