I have a little metraphot 3 that I sometimes use. It has a selenium cell. I had another handheld meter that was banged up but still had an active cell in it. It was a simple matter to trim the selenium cell to fit and surprisingly it didn't take any fiddling to read correctly.
edit: I did a little googling around and see there is a sort of tutorial on how a guy used a selenium cell from a solar powered calculator to repair his Metraphot 3
