Item is NOS (new old stock) OEM Clock Key  Please review photos of close-up photos of keyway

Vintage Clock Key as shown in photos - This is an older vintage key not a newer remake. Appears unused.

Key sizes by numbers vary amongst different countries and makers - why I added a millimeter measurement.

I round down the measurement to the nearest 0.25mm

Make sure your key is slightly larger than the square post it is to fit to insure a good fit.

Size measured by micrometer and is approx.
