Kodak Super-XX Type 120
Kodak Super-XX was introduced in 1938. The Kodak Films brochure published by KODAK Australasia in January 1956 mentions the film in the main text but includes the data sheets only for sheet film. Apparently, by that time Super-XX was discontinued in roll formats and replaced by TRI-X. This gives us a time period from 1938 to 1956 for the images on this roll.
The roll was processed together with the Verichrome in HC-110 dilution B at 5 °C for 12 min 30 s.
The location was identified by the iconic buildings of Karachi: Central Post Office and Merewether Tower.
