Thank you. I never would have guessed the stripeys were so early. Winnie said that she had a for sure pre-WWII box of marbles with them, but still I couldn't wrap my head around it. These days my memory is not serving me very well but I will try to make a place for this.
Like why did they pay Christensen so much for his patent? 0_o And how did I get the idea that he made such great bearings so efficiently?
Oh well, he got the money, we got the marbles, and I had a magical bike ride beside my lake.
I know ball bearings existed before his patent. But I thought his process was considered a quantum leap up from the older versions. More reliably round, lower cost, and possibly better physical integrity.
Do you have reason to believe that his improvement/variation was not employed in manufacturing ball bearings?
The money he made from the ball bearing patent allowed him to retire from his previous profession and start his marble business.
Now that would have been an interesting series of thoughts and discussions ... following how Martin came up with the idea of going into marbles and making the marbles in a way that no one else had ever done before.
