An interesting link to a 1946 magazine (Popular Mchanix ?) , thanks for posting… I lot more stuff to see if you keep scrolling down, even a 1946 Evinrude ad. And of particular interest to the folks around Detroit, there is an article showing the concept drawing for the future GM tech center in Warren MI.
I did not realize thre was 306 pages of stuff to read not bad for probably 50 cents at the time
Dad had one of those Dremel tools in the metallic case …Carhart clothes already had 50 years of experience in workmans clothes !! wow
