This chaps videos are just the best if one is interested in slide rules which I am . fascinating little machines .I used them in college 50 years ago. I have the N4-ES and the white N4-T . I must say I find the white T slide rule easier to use.
Flying Fish also made other vector slide rules including their model 1004 which included hyperbolic scales: Th (from 0.1 up to 3 radians), Ch (from 0.2 up to 3 radians), Sh2 (from 0.85 up to 3 radians) and Sh1 (from 0.095 up to 0.9 radians).
Yes, they made quite a diverse line of rules. These two share a lot of similarity though, so I think the 1003 is most comparable to the N4. I'm actually obtaining a couple of other FF vector rules, but I won't have them for some months.
@@ProfessorHerning I own a Flying Fish model 1004 Slide Rule and am very pleased with it. Its scales are as follows. Obverse Side Upper Stator: Th, Ch, K, A. Obverse Side Slide: B, T, ST, S, C. Obverse Side Lower Stator: D, DI, Sh2, Sh1. Reverse Side Upper Stator: LL01, LL02, LL03, DF. Reverse Side Slide: CF, CIF, L, CI, C. Reverse Side Lower Stator: D, LL3, LL2, LL1.
Nice general purpose layout with hyperbolics. The Ch scale is a little less common, but nice (without it, cosh is usually calculated on rules as sinh/tanh, but this is a somewhat awkward solution).
José7 José7 Does the pocket version of 1003 even exist? The closest I saw is 1200. But it has different set of scales. sliderulemuseum.com/MiscWorld/FlyingFish_1200_DuplexLogLog_GiftOfLeroyHauslerCollection.jpg
I should have mentioned that! A lot of the Asian home-market rules fold at sqrt(10), but yes the Pickett and basically all American rules are folded at pi.

The leaning letters are reminiscent of the leaning numbers on the circles of the Transits of that era.
Would these slide rules be vulnerable to atmospheric conditions on a submarine?
Nice video.
I prefer the pocket versions of these two slide rules.

Noteworthy is the the Flying Fish CF scale folds at the square root of 10. I don't have that Pickett rule, but I'd bet it folds at pi.
