Translation assistance bitte!
This is extremely off topic, and I apologise in advance! However....
I bought something interesting at an antique place today. Problem is, I have no idea what! It is some kind of weighing / cutting / sample preperation device. The only clue I have is that on the wooden box is printed
des instituts fur
As far as I can tell Glasblaserei is Glass Blowing?
GARUNGSGWERBE is refining trade (refining of what? Glass? sugar? oil?)
I seem to be losing something in the rranslation.
Google throws up some sites, but nothing seemingly relevant.
Any clues anyone?
