Vintage Hand-Cranked Roll Film Magazine Back with Cover
Unknown, 1930
About the object
This heavy-duty technical camera accessory features a robust cast-metal mounting flange coupled to a hand-cranked internal transport mechanism. The central rectangular sheet-metal housing encloses a roll film or paper feeding assembly flanked by precision rollers and operated via a top-mounted crank with a turned wooden knob. A form-fitting black sheet-metal protective cover with dual wire bail latches and a turned wooden carrying handle encloses the unit for transport.
About this object
Industrial-grade hand-cranked film magazine featuring cast frame and lidded hood
Condition
The unit exhibits authentic age-related patina across all painted and bare metal surfaces. The black protective hood retains solid structural form with minor surface scuffs, localized finish wear, and light oxidation along the edges and base flange. The internal mechanism shows intact wrinkle lacquer on the cast frame, honest mechanical wear around the crank assembly, and sound structural integrity throughout.
