Record status
Individual type · partial
Period
1972-85
The camera is finished in chrome and carries the serial number 57113. This specific unit is identified as a unique prototype variant modified to accommodate 128 exposures, significantly increasing the standard capacity of the Alpa 10s model.
The internal modifications allow for a specific frame size measuring 10mm x 24mm. Complementing this adaptation, the camera features a specialized film counter mechanism that reads up to 128, distinguishing it from standard production models. The shutter mechanism is reported to be in working order. As a body-only unit, it displays the characteristic design of the Alpa 10s system, characterized by its robust construction and ergonomic layout typical of Pignons manufacturing from this period.
This item represents a significant technical curiosity within the history of Swiss camera design, documenting experimental efforts to enhance film efficiency for specialized photographic applications.
