Which Battle Ship had compass patent number 185/43
-
... but not just any ship.
A friend is looking for a vessel, possibly ww1, that had the compass patent number 185/43
Attaches is a picture of it - sorry its from a mobile phone.

Hi, I could be wrong, but, if the patent number is for the design etc of the compass then there could be possibly hundreds if not more of that type of compass in many ships.
I fear that if I am correct then you would have very little chance of finding that particular ship.

A patent number was indeed granted for the design. ;D
You need to find the make of the compass and a serial number, in order to identify (possibly) on which ship the compass was on.
Patents issued up to 1852 were always a number, a slash (/), and a year number (4 digits).
So something like 652/1750.
From 1852 until 1915, patents were numbered from 1 each year - so the year is important.
From 1916 until 1981, it was a 7-digit number.

I have a ships compass not unlike that one. it has its own box and admiralty annual inspection report, to me this suggests, that a ship had many compasses in its lifetime, and the navigation officer would get a replacement from admiralty stores when needed.
they must have had a spare one on board anyway :-\ :-\ :-\ :-\
