240Z: STE Synchrometer Carb adjustment toolbox

As somebody who used to develop test equipment and test procedures as a profession, I just love special tools and equipment and when they’re for one of my cars, I always collect them.
Recently, my mate Florian found a pretty much complete set of an STE “Synchrometer” for Nissan / Datsun SU (Hitachi) Carbs.

STE stands for Shleyer Test equiipment and is a german Company who used to make those, in what to appears some kind of Partnership with Datsun / Nissan Germany back in the day. The company still exists, but only seem to sell their Standard product now.

The tools come in a nice wooden box with a variety of different adapters for multiple cars

And a set of adjustment tools in a little pouch, including instructions.

It looks like STE made a wide range of sets and adapters for various cars.

But this set is specifically put together for Datsun cars, which you can see by the included manuals by STE specifically for Datsun cars.
The second set of document sincluded is (what I think is) a Datsun / Nissan Germany Service journal, which explains how to test / set the carbs using that STE Synchrometer set.

Overall, maybe not a tool I will use very often (Especially, since I plan to use triple Mikunis), but nonetheless a very cool piece of german Datsun history, and given the condition it has, also a nice piece for my display of rare and cool Datsun / Nissan tools.
