Whatever you do, I think it would be a shame to break this mechanical wonder.
Well, my occasion flew on to Australia without stopping here, and the thing is not worth the cost of mailing it.
Looks like it stays put for the time being.
It's a bit faded and scratched (like someone was washing around the numbers over and over and over and over and over...), but is fully functional.
My 10 y.o. nephew loves it, for some reason he find it fascinating to see the numbers on a box full of cogs and gears to match up with the numbers on his cell phone's calculator.
