Yea, my Grandfather worked for Philco during the war. Every nut, bolt, piece of metal, tube etc was all made in house.
My buddy was a blacksmith at the Phila Navy yard, every tool etc was made in house.I was at his house and he had some really nice drilling hammers , best I have ever seen, I asked him where he got them and he was like " I made them".. now everything is china junk except Snap-on, Mac, Channelock and Matco tools
