Another Trivia Question! 10pts to right answer!?

[BearBear]

You could possibly receive 10 points if you can tell me what this is AND how it was used. http://www.prices4antiques.com/item_images/medium/43/48/81-01.jpg

If someone answers the question with the correct answer I will award that person with 10 points. If there are multiple correct answers, I will let the question go into voting for a day or so. Once it is there, people will vote for what they think is the best answer. I will look through the answers and then award the 10 points to the correct answer with the most number of "thumbs-up" votes.. Happy hunting!

Also, if you think you find the correct answer, please do not put a link up to where you found your answer. No cheating.
Remember to say HOW it was used.

You put flys or other things of that nature in the tube thing to examine and watch for scientific reasons.

coin operated dice popper and built in cigar cutter

After inserting a coin, the person would put a cigar tip in the hole at the top. While turning the knob, the cigar tip would be cut off and the dice would pop.

Isn't that like a boggle dice shaker? I used it for the game boggle when I was younger.
