Here are two almost identical developing tanks, reels, thermometer/agitators, and instructions.
Only the names and boxes are slightly different.
The tanks are perfect, like new.
35mm, 120, 620, 127, and 828 films will load "automatically".
Someone once told me that these reels can load subminature films, but I've never tried it.
The reels load the film effortlessly...I tested them with a 35mm 36 exposure dummy film.
The thermometers are not functional, except as agitators.
Instructions and boxes are in good condition.
Kindly specify which one you prefer.
$10 each + postage.
if these take 16mm or other sub mini i'd be very interested
I think it works like this: you remove the bottom half of the spiral, the clear spiral, and REVERSE it back onto the spool.
Then, the spacing is about right for 16mm/subminiature films.
Of course, there's only one set of grooves remaining on the other spiral, but since submin films are relatively short, that shouldn't be a problem.
Anyway, that's my guess, but I'm not certain.
Perhaps somebody else can answer your question with 100% accuracy.
One tank sold.
One tank remains for sale.
By the way, the Priority Mail shipping cost is $5.20.
Postage rates increased last week, so the Priority Mail cost is now $6.
