Got lucky the other day with a good find, two pristine condition Minox thermometers, in their original cardboard casing. They are of the older model, the one with a metallic loop supporting the inner alcohol tube.
I consider this to be a good acquisition, mainly because these items are getting scarce by the day. And of course, not to mention the excellent condition they’re in. Not very many in such state out there, as far as I know.
