Also contact me if you need to see more photos or higher quality photos.
I forgot to measure this or put a ruler in the photo,
it is less than 4 inches long, about 1 inch wide.
The top piece is not broken, it rotates about that round pin.
The top piece then slides back less than 1mm,
and something tiny rattles inside.
How do I open this without breaking it?
It may be from Germany; age is also unknown.
