Curta Type I value and a mystery

From: Keith


AN upcoming taping of "The Computer Program" will feature (among other things) my old Curta coffee-grinder.

Can anyone give me an idea of the current value of Curtas? Mine is in VG condition (except for the mystery), works just fine and is in a metal canister.

The mystery has to do with the bottom plate, which has two countersunk screw holes . . .but no mathing holes inside the calculator!

This means that the bottom and housing can be removed. Is there something missing from this calculator?

If anyone can give me this info, thanks!
