Following up on my original post, I've scanned and virtualized my Pickett N4-ES Vector Type LOG LOG DUAL BASE SPEED RULE. That's the most complicated rule that Picket produced. It has 34 scales, which is good, because in the world of slide rule collecting, bigger is better. ().

Have fun!!
I don’t need this one. I’ve got my own in my office drawer.
My first year of college chemistry 101 we had a test where we had to compute the number of moles, of whatever it was and it was a simple problem. When I was attending Tech, at least that first year, they still used slide rules although those spanking new TI-55s were just coming on scene.
I still had the slide rule, and the problem was actually an exercize if you knew how to use one....add/subtract instead of multiply/divide using logarithms....
About the time I finished the problem, I heard a bunch of moans and glanced up around the lecture hall and I saw a bunch of TIs/equivalents with their LEDs blinking “EEEEEEEEEEEE....”
The prof set it up where they’d overflow....
And somewhere in the basement, I think I still have a Frieden. Wonder if it's worth anything..or worth enough to did around for.
Pickett N3 ES
K&E Deci-Lon
K&E Log Log Duplex Decitrig
Hemmi 259D (the rule I used in school)
Faber-Castell 283N (IMO the coolest rule ever)
Not that either one did me much good. I flunked out of Differential Equations in college...
Or as my daughter would ask - is there an App for that, dad?

Really interesting. They were gone by the time I was in any school at all.
How did you make that?
By the time I went through school we weren’t taught to use these. Thanks for sparking a few minutes of interest... I can kind-of do basic multiplication now :P
That is TOO COOL
Cool! Thanks.
Great post! My Dad used his to design electrical equipment for the New York City and other subway systems, the monorails at Seattle and original Disneyland, and rail cars that dumped the cement for the Glen Canyon Dam in AZ. It was literally the last item he removed from his desk when he retired at age 80, though he’d switched to computer long before then.
I have a Pickett All-American hanging on the wall of my office. It is 4 feet long. When people ask me about it I tell them I use it for really big problems.
I don’t have a slide rule, but do have a Curta Type II calculator in its original box with original instructions thta I bought in early 1970 to do estate and tax work. In 1971 the first of the electronic calculators came out, making my Curta instantly obsolete, so I decided to keep it as a curio that might someday be very valuable. Right now it’s worth about $1,300 vs. the original price of about $150.00.
I still have my K&E log-log-decitrig that I had in the 50s in college, I still carry it in my glove box in my pickup.
Why would I want to be tied to a computer, when my Post slide rule is right here in it’s leather case on my belt?

BTW, AWESOME page!
