I had a grandfather that restored a 1914 Ford Model T, and a 1918 Essex to showroom quality. They even went on a European tour with one of them, and maybe China too. He also had & restored one of the only two remaining 1928 Viking Roadsters. The only other one was on display at Harrah's in Reno. Plus he restored several other antique cars to show quality.
Anyways, his garage shop was full of Ford & Oldsmobile specialty tools, as I remember. Only saw his garage shop a couple times, as he and my Mom were estranged throughout most of my childhood, thence thereafter he & I were never close, even though he lived only 10 miles away on the other side of the city.
But I remember him showing me how he had to fabricate many sheet metal and even forged parts for the vehicles and their engines, as well as replacing/rebuilding their wood framed convertible tops!
Anyhow, didn't mean to ramble-on so much; this thread just reminded me of all kinds of special Ford & Oldsmobile & other old-timey tool brands that I noticed throughout his garage on those two nighttime visits he took me on therein.
But to ramble-on a bit more, I think he started-out as a general laborer at a wire & cable manuf. company called 'Wire Rope Mfg. & Equipment Co.' of Seattle, which made giant cable systems for skyline tramways, and railway street cables, and logging co's &c.
Then at some point was hired as an apprentice mechanic at the Seattle Oldsmobile dealership, working his way up to journeyman mechanic, and later-on built & owned the first two Oldsmobile dealerships in Alaska. And made millions by having one of the prime sales distribution lines, of myriad general goods & pharmaceuticals, including running bootlegged liquor to Alaska during the prohibition, &c.
And in case anyone's wondering....no, not a single tool or anything else was inherited by my side of the family.
And moreover, I don't remember why or how he and my Mom had their falling out. But no one is left to ask.
Moral of the story . . . Try to do recorded oral histories with your elderly family members, before it's too late, and they're gone. Don't put it off, thinking you have plenty of time.
