No, it isn't important. I was just curious. I don't think my mother would
want her inkwell taken apart again just to identify the screw. I just
wanted to know what "standard" the French would have used in 1944. That is
all.
Glückliches Neues Jahr!
Happy New Year!

Try a hardware store, John. As I recall either the Home Depot or the
Lowe's (or both) stores near us have a thread try-gauge. I've got one
here at home, if you're desparate and want to ship me the screw.
