A fine example of Maitani’s masterpiece. Black OM1n with 50mm f1.8 and brown leather case. Given a service recently with new light seals and foam removed around the prism. No degradation to silvering on the pentaprism. Running on zinc air heating aid battery with brass adapter. Meter is accurate and fully responsive. Shutter speeds all there and within tolerances. Hot shoe intact but cracks appearing. Bottom plate has heavy brassing. Lens clean of fungus. A few specks of internal dust. Aperture clean and responsive. Leather case in good order.
