Really sad for me since I'm ("was" now) on a very active SLIDE RULE group. Lots of mind numbing hypothetical math implementation problems for SR's, history, questions from noobs, questions and answers about obscure rules, etc. They helped me find my missing SR (well the same company and model anyway) that I lost on a bus in Taiwan in late 1970.
while there is a great Slide Rule Museum site there are no discussions there just lot's of pictures of beautiful SR's, manuals for download, upcoming SR competitions - yes there is an annual SR competition - LOL, history...
https://www.sliderulemuseum.com/Visit the museum if interested in old stuff that involves actual intelligent thought processes and not mindless key punching with and lots of pics and some of those are part of my Dietzgen collection (I also have a large Pickett, Farber, K&E, Hemmi, Chinese made, and a few others but they aren't posted there)
