Excellent advice :-)

What apparently caught a lot of owners out was the hand-fitting of seemingly identical components. Correct reassembly required keeping the fitted parts together with their mates.

The good news is that they're pretty robust and don't typically *need* disassembly.

My Curta 2 was a refugee from a coal mining operation and didn't work when I got it. The "repair" was just removing the outer housing, flushing it with solvent to remove a couple of decades of coal dust then applying a little oil and it was back in service.

Last year the water tower near us was repainted.
I was surprised to see that they "sandblasted" the old paint off with coal dust!
