r/Sliderules

I made a slide rule using two sheets of paper. I used my ti-84 to get the logs, and placed the numbers in their respective places on a linear scale. It's not the most accurate, but it was a good way to burn an hour of time.

Not knowledgeable on these, just found out that this model should be from about 1958-1962. Honestly wondering what these go for in selling. Any info appreciated, thanks!
