A river-flow-meter set
(Durchflussmeter)
.
This set was used by the Finish army, and is "SA" marked. No German
markings (and priced acordingly), but identical with the German model
made by Oculus. I suspect it was manufactured in Germany and imported
to Finland by the company marked on the ruler. The last two pictures
show it in comparison with a German set. Used by engineers and
pioneer soldiers to check how rapid the flow in a given river is when
preparing river-crossings. Very rare kit! $ 130,-
