Someone is still making slide rules

My first calculating device was a Concise Model 700 circular slide rule. My older brother won it in 1975 as the recipient of the high school science award. He didn't need it so gave it to me. When my high school chemistry teacher required each student to have a slide rule, I was ready.

I won the same science award in 1981 and received a TI-55. That 55 died long ago, but the circular slide rule is still in the my desk drawer right next to me.
