Rolleicord IIc Model 4 – Model K3 – 542
The Rolleicord was a popular medium-format twin lens reflex camera made by Franke & Heidecke (Rollei) between 1933 and 1976.
The models that has the letters DRP on the left and to the right DRGM on the front of the camera means that they were made before World War II, because DRP means ‘Deutsches Reichs Patent’ (German Reich Patent) and DRGM means ‘Deutsches Reichs Gebrauchs Muster’ (basically a copyright for the name). In post WW2 models you will find DBP and DBGM. They switched from “Reichs” to “Bundes” (German Federal Patent).
