Since we're in the groove as far as guessing what something is I thought I'd post this one.
Picked it up last fall at a fair outside Oslo.
I was lucky enough to have some people with me who had seen this before so I know what it is

It's a 3.5" long, approx 2"1/4 wide. The "roller" is hollow glass, the "base" is pressed and cut crystal.
Made at Høvik or Hadeland.
What think ye?
I will post an explanation on it's use later
