I recently picked this little guy up as part of a mixed equipment lot: "The Gem Refractometer" by Gem Instruments. I was shocked to see that in person it makes a Duplex III look big:

It must be an older product, since it has a hefty metal body (smaller than the duplex III but heavier). I don't know as much as I'd like to about the history of Gem Instruments, but they did always make great stuff. Has anyone seen one/have a sense of the rarity?

I remember when those were sold.
Portable pocket instruments.
Very cool!
