Description

German aircraft compass taken from L.V.G CV two seater biplane shot down at Afule, Palestine 1918.

The item comprises the compass bowl from a German aircraft. The internal parts are missing, as is the compass needle. The instrument is comprised of two main parts – the cylinder that comprises the upper portion and a bowl that attaches to the bottom of the cylinder. The overall height of the instrument is approx 85 mm.

The cylinder is approx 57 mm in depth and has a 115 mm dia with an opening of approx 85 mm dia. A metal ring approx 7 mm wide is attached to the top of the bowl and is inscribed with degrees at 15° intervals (0, 15, 30, etc.). On the outer edge of this ring is embossed “CARL BAMBERG BERLIN.FRIEDENAU Nr. 17276” This starts at the 150° and finishes at the 240° positions.

Inside this outer ring is another ring that has the 15° intervals marked by an inscribed line. It appears that theses would have been originally filled with white paint. This inner ring is sloped downward into the bowl.

At the 90° and 270° positions on the cylinder section there is an attachment point where the compass would have been mounted in a gimbal.

A vertical needle is fixed in the centre of the bowl by a metal ring with a cross bar. The bottom of the bowl is a brass(?) plate of concentric corrugations. The base of the instrument (bowl) is screwed into this by four screws. Inside the cylinder at the 0°, 90°, 180°, 270° positions a metal clip is screwed into the metal ring. These clips hold a vertical metal bar that is assumed to be the means of aligning the compass initially.
