Publisher's Synopsis
Excerpt from A Remote Controlled Underwater Photographic Surveillance System
The existing film supply roller is moved under the front opening (film inlet) to prevent film scraping. An auxiliary takeup film roller is installed under the rear opening (film exit) for the same purpose. Holes remaining in the lb-4a magazine, after modification, are plugged to prevent light leaks. A conversion kit is available commercially.
