Woo hoo, having had a Pen-EE (sort of an older, smaller, half-frame, similar looking, similar working camera - except no focussing at all) for twenty years I just saw a Trip-35 in a junk shop here. For seven euros I hope I have found a reliable carry-all-the-time camera.
The camera itself is very clean but the case is falling to bits with old-plastic-fatigue(?!), so I guess it has been stuck in someones attic cupboard for years.
Also the front part of the lens housing, with the asa settings, is quite loose yet without apparently affecting either the lens-mount or the mechanism below the lensed-window. Is that looseness a typical "feature" ?
