The Black Topcon R (VERY RARE)

The Topcon R was the first single lens reflex camera manufactured by Tokyo Kogaku. It was introduced in 1957 and was the first Japanese SLR with a semi-automatic diaphagm. 99 percent of the Topcon R cameras produced were in chrome finish. A very small number, less than 100, were manufactured by Tokyo Kogaku in black enamel finish for the National Police Agency of Tokyo.

The camera displayed here is probably the rarest SLR Topcon camera ever produced. Most uncommon, particularly outside of Japan.
