Never used one of these, I have serious doubts that it is water tight if inverted.
Agitator thermometer is missing. It engaged an octagonal socket so a replacement from plastic sheet that spans the long diagonal ought not be hard to make. Or put the reel in a different tank.
Original box and instructions incl. and appears unused.
accepts film sizes: 16mm or 110, 126, 127, 120, 220, 620, and 828.
Some of these are hard to find reels for but film stocks are available for some of these Orphan sizes/formats thru lomography etc. now you can develop them at home.
