Out of respect for @Susquatch I'm not showing the cases:
And I was mistaken: Dietzgen Microglide™ (Decimal Trig Log Log). The 5" is a Pickett N600-ES, Aluminum Log Log Speed Rule (The Official Slide Rule of Apollo).

I have a couple, including the circular one I got when I was around 13. Never moved up to a cylindrical though...
...which reminds me of how I've been thinking about getting a dial caliper, because reading those lines on the vernier (like on a slide rule) is getting harder, and the digital ones eat batteries.
Also have a Soroban, which I never mastered, but did get far enough into to realize that expertise in using it is kind of like playing a musical instrument - muscle memory, and not having to think about what you are doing because it has become automatic.

You mean like rolling your thumb over the slide to get fine adjustment?
I used a slide rule in university and my first calculator was a used HP45 that I repaired. I programmed an HP41 to play good chess. My favorite calculator is an HP15C. I have one on my desk. But I also have an emulator for the 15C that runs on my Android. It's a really cool app.
I raise that to 25. I was Asked the time the other day and said it was 15:30. Just blank stares. Not only can they not read anything analog they have no idea what 24 hr time is. I actually instruct on how to read analog meters and it can be really tough. Simpson 260 meters Seem to be voodoo to some.
Back to the op I have two slide rules, I would have to dig them out, a Small one and a large one. I’m currently moving but if I see them I will post em.
If you have an android smart phone, you can install a clone of Hewlett Packard's HP-15c. That way it's always with you no matter where you go:
HP 15C Scientific Calculator - Apps on Google Play
The authentic HP 15C Scientific Calculator App is now available.
In landscape mode it has a full replication of an HP-15C including storage and programmability.
In portrait mode it has an abbreviated easy to use keyboard for regular RPN math.

iPhone Calculator in Portrait
Changes to an HP-ish layout in Landscape
Only without the clunky (I'm sorry, I had an RPN HP when I first started in industry – didn't need much of a calculator when driving ships – and even after using it for months I would forget to use the dam Enter key) RPN interface. I use the landscape version when working with functions or more than 9 significant places.

I basically went from pencil & paper to the metric conversion calculator when Turd 1 created that turmoil...many hundreds of thousands of dollars were spent at that time because of poor calculations made in the dirt moving business & farming ,both of which I was involved in at the time.

Hell kids can't use a cell phone to TALK to a person they must text or social media and it drives me nuts. Sometimes a plain old person to person conversion is what is needed.

There is some hope, my now 16 year old nephew has a growing collection of watches - all analogue.
I think I'm gunna start a special dedicated tool drawer for my Slide Rules & HP Calculators. Each one will also be in dedicated clear plastic containers with opaque lettering labels on them........

I have a few slide rules, although I am too young to use them properly. My favourite one is a Pickett that came out of Bristol Aerospace in Winnipeg.
In High School my calculator was an HP-38 E/C. (I don't remember beyond the 38)
Wish I would have hung onto it. It got tossed in one of the many University moves I made.
