This is a WW1 period Imperial German Tripod mounted artillery director dial sight (Richtkreis) by C. P. Goertz, Berlin. Richtkreis translates into English as aiming circle and was used by the Germans to direct artillery fire. The eyepiece shows a thin centreline with markings from bottom to top of 0 to 60. The top of the director has a levelling bubble and a compass needle which can be locked. There are various nickel plated brass knobs for levelling and using the director. The base where the director mounts is graduated from 0 to 32 in both directions. The director retains much of its original grey finish with nickel plating to the adjustment knobs. Both levelling bubbles are intact and working. The director is marked C P GOREZ BERLIN and Rhr Nr 2562 (serial number). The director is mounted on a small square bevelled mahogany plinth. The price includes U.K. delivery. OPT 904
