With the introduction of high speed Type 47 3000ASA film in 1959 some of the older cameras required retrofit light proofing seals. Cameras manufactured with light seals had an L prefix serial number.

The kit for the 80 and 80A cameras comprised a chenille wire and plastics strip to seal the camera body, a metal cover with a rubber grommet that fitted around the I-B switch on the camera lens board and a grey plastics hood to fit over the top of the lens board blacking out leaks from the EV number window and wheel.
