Reply With QuoteI wonder is it some type of viscosity meter.
Like something that times the drop of a solid (sphere) through a graded column of liquid to determine viscosity ?
Hi all
Picked this up this morning. German text. No military markings on case. Presumably some sort of artillery timer? In all my years of collecting I’ve not seen one before.

I tried Google, and searched for 10.5cm flak
https://en.wikipedia.org/wiki/10.5_cm_FlaK_38
The 10.5 cm SK C/33[Note 1] was used by the Kriegsmarine, the German Navy. Related to the Flak 38, it was installed on the Bismarck and Scharnhorst classes of battleships as well as the Deutschland- and Admiral Hipper-class cruisers.
After the war, it was used for a few years by the French Marine Nationale on the reconstructed destroyers Guichen and Chateaurenault
The offset on the dial is likely be for the correction needed depending on the target distance.
Interesting. Thanks. I just found this

Nice find Ian, regardless of what it measures, it's cool.

Maybe it’s missing its secondary case. Does it have a 19 ligne Minerva calibre inside ?

The movement is indeed a 19 ligne Minerva. Thanks.Originally Posted by HookedSeven

I reckon that’s what it is then. Would also explain why there are no military markings as they are found on the outer case.
Does it work foggy ? what movement inside Swiss made or German made ?
Thats a interesting find ,Boot Sale ?
Sorry ignore the question its Swiss !
Yes, all working. Fast moving sweep hand, takes about 12 seconds to complete one revolution. Cool thing.

Interesting find. I did some research on Vo = 785 mls and found this
http://www.lexpev.nl/downloads/ringbuchinfanterie.pdf
It’s relating to calibre of bullets. I’m only guessing but I think it’s relating to time of bullet from being fired to impact depending on range, elevation and size of round 16, 24 or 32mm.
It’s the initial velocity of the shell. So V for velocity and a small zero for time = 0. The units are meters per second, so it’s m/s not mls. 785 m/s is about 1750mph...
I think !
Sounds about right.
