Just figured out today that the dates for 1970 line up with this year. When my grandfather moved to an assisted living facility, he let his grandkids go through and pick things from his house. I chose a pinball machine, a bike, a chair, some tools, and Hilda. I love her. It makes me very happy to be able to re-use these. With 1970 being one of the earliest ones he had, I am going to be set for a while.
Mostly a farm hand and carpenter, contracting work. He did a lot of jobs. But we also had a lot of UAW guys like my dad and uncles in the family, from the west side of the state. I suspect he may have got it from one of them. Muskegon area.
