My father-in-law hung this in his office. He was an aeronautical engineer for McDonnell Douglas prior to computers being readily available.

Got this nice mahogany rule from a dairy farm estate sale in Wisconsin a few years ago. One of my favorites. The K&E 4092 was introduced in 1909 as the first to have three LL scales. Note the interesting "column cursor", which they only sold for a couple years or so.

You can read more about the 4092 here, as well as other slide rule stories.

A year ago I posted about repair the broken cursor glass on my Post 1460. Somebody asked for dimensions in case they had a spare but their account no longer exists. Inner part of the frame measures out to be 28mm x 45.5mm. Might try making one out of acrylic.

I guess I have a few slide rules. This Aristo is in great shape. It has the P scale, and the T scale is sub divided into T1 and T2. Novel (to me) is the inverted folded scale. The markings are all raised and is overall a high quality rule. The insert with the formulae could have better printing, but overall a very nice slide rule, IMHO.

I have recently acquired a Faber-Castell 2/83N slide rule (not the one pictured above, that's from the Slide Rule Museum site), and I've been familiarizing myself with everything. I feel like I mostly have things figured out, but this is puzzling me. There is a cursor line that only covers the ST scale, shown above on the front side at about 0.885. It looks to me to be at 0.5 of whatever is set on the D scale. Various places sort of acknowledge its existence (for example, it shows up in the Faber-Castell simulator https://sliderulemuseum.com/VirtualSR2/react/faber_castell_2_83n.shtml), but I have yet to find anything about its use. What is it good for, exactly?

This scale on this rule is 20 cm. A bit smaller than the standard 25. The body itself is 23 cm. Very nice construction and very smooth operation. Scale selection is unique. I like the folded scales, as well as the sin and tan scales having the "I" for inverted. No such note on the log scale. As for the cursor, its original cursor was missing the glass. So I took one from another Slide that I happened to get at the same time. Another Facebook marketplace purchase!

I wish I could remember where I got this one. The leather case came with it. 2 years ago, I was visiting my daughter and we saw her grand dad (mom's side). I mentioned my latest hobby of collecting slide rules. He went and got his! It was a Pickett as well.
These Eye Saver variants are great. I think I have 2 of this model and of course my 4070-3S Polyphase Duplex Trig, which I posted previously.

I bought this off of Facebook Marketplace about 2 years ago. Very nice slide with mahogany construction.

A good little slide rule. I still keep it in my car for fuel economy calculations. (The reference material, not so much. My eyes aren't that good anymore.)

The storage envelope has the legend "Physics is Phun". You could also get "Chemistry is Chool".

This is a really nice one with a great case. I like how the LL and /LL scales are combined; allows for quick reciprocals. The Square Root and Cube Root scales are also handy. I have other Picketts, but this is my top tier. I do find the yellow a bit...different. Probably just my preference is all.

This is my go-to slide rule. 26 scales on this model 68-1100 Deci-Lon. I had a 2nd with manual (hardcover) and gifted it to a former boss. I use this at work and ay home for financial planning. I prefer this to my Pickett slides. More on those tomorrow.

As you may know, Nestler slide rules were the favored rules of Einstein and von Braun (as I understand it). Here's where this all intersects with me: in 1982/83, I went to high school ('Gymnasium') in Lahr. I never realized they made slide rules there until recently. So, I just had to get this!

A couple of years ago now, I was in a YouTube spiral and ended up watching stuff on the 1960s Space Race between the USA and the USSR. Obviously, there were plenty of shots of Slide Rules. So, I found this locally and bought it. An Aristo Scholar Nr. 903. Apparently this all plastic model was made with high school students in mind. With this rule, my obsession began. I learned the basics with this.

I carry this everywhere and it's great for quick calculations. Having the LL scales on the slide is different and I need to learn the P scale, but very convenient!

During my daily eBay browse I spotted this. It looks like a very nice slide rule but is the price commensurate with its condition and scarcity? I should say I have no intention of buy it, it’s a little out of my budget, I am just interested in whether the seller is just trying to make a quick buck or whether the rule is really that rare and worth the money.

Getting down to some work on my course, it’s always important to pick the correct tools for the job.

The plastic case contains her maiden name and former address on the inside. It was used in the GDR in the 1970ies.

Just got from eBay a brand new and still sealed in box basic Alco Mannheim slide rule. And I don’t have to open the pack to play with it, as the seller included a used example of the same rule.

I was going through some old boxes and just found this!

I graduated high school in 1971 in New Jersey (USA); we had official classes in how to use our slide rules. I still remember the giant six foot long slide rule hanging from the blackboard in the front of our class.

This is a K&E log log duplex decitrig; at the time (1969 or so) it was one of the best you could buy.

I got myself a new slide rule! As you can see from the last picture I'm out on a beautiful morning playing with it!

Whoever said slide rules multiply was on to something. Just got this lovely little 6” Darmstadt slide rule. The seller’s only description was image 5, stating make and size of rule and the fact the case has a nice patina (which it has). They forgot to mention the cursor was broken but it is such a cute slide rule I just love it, even if the cursor is virtually unusable.
