Back in the '80s-'90s I did a lot of landscaping jobs as a side business. My workhorse optics were a Sokkisha level and transit. When "total stations" started to become popular, you could find some high end old school optics for a cheap price. I started collecting some Wild Heerbrugg, Kern, Sokkisha, etc. Some I've sold or given to friends/relatives. Here's a few I dug out while cleaning & organizing a storage cabinet. There's a bunch more stuffed in different places.
Wild Heerbrugg levels: N1, NK1, N2, NK2,NAK2,N3 (one with erect eyepiece), Kern.
T2 & T3 Theodolites

When #1 son graduated with a civil engineering degree I gave him this for his office. The world's smallest theodolite: Kern DKM1 If you look close, on top center you can see the North finding compass that I found years later after buying the little theodolite.

I've also collected some WW2 optics. US Navy "Quarter Master Spyglass" (16x mag.) "Officer of the Deck Spyglass" (10x mag.) Both with exceptional optics and matching # cases. The QM glass is wrapped with tarred cord and fancy braid.

That's a small Japanese optical distance range finder in front of the boxes. Cleverly packed away somewhere here, I have a Japanese military trench binoculars and I believe the counterpart to the US Navy QM Spyglass: A very high quality 40x Japanese draw telescope. I'll have to find them and post some pics along with some other oddities.
Here's a WW2 Japanese Army (I think) Engineers/Artillery ? transit with a precision compass and other goodies. The case is its own backpack with pad and straps for its soldier. It has individual magnifiers to read the altitude & azimuth circles. Pretty fair optics for a wartime Japanese transit.

If anybody can read Japanese "Kanji" I'd like to find out the translation of the case's Kanji lettering. I can take a pic of just that.
