Note: 599961 model 940.
The description describes the jewels as ruby.. I
note that on my example, one of the visible jewels
is clear. Could it be Safire or Diamond? Possible
a retrofit?
Curator Response: The Grade 940 plate jewels should be ruby. If one of the plate jewels is clear, it is a replacement.
