Mamiya lens hood for 180mm f4.5

Description

This absurd box-shaped thing is the official hood for the Mamiya-Sekor 180mm f4.5 and 250mm f6.3 lenses. Slips over the taking lens and fastens with a thumbscrew; it also shades the viewing lens because that’s just polite. In very good condition, with minor surface marks from normal use and handling, no cracks.
