Rolleicord Va 1019
Photograph of Ferdi’s Rolleicord Va with a Rolleinar 2 in Bay I. The Rolleicord Va is equipped with an exchangeable exposures counter. The standard counter is for 12 exposures of 54×54 mm. Counter sets for 16 exposures (40×40 mm) and 24 exposures (24×36 mm) were available. The sets provide the proper masks for film and finder. The counters can be exchanged by the user. The Rolleiflex Vb had the same options however the sets are partly different.
