Pearl Dry info?

I just got this Pearl Dry razor from my Dad (see intro post) and am having difficulty finding much information on it. One thing I noticed is the lettering, inlay and scales are exactly like the Dubl Ducks Goldedge razors. So are Pearl Dry's related to Ducks or did they just use the same vendor/manufacturer for the inlay and scales? Any help is appreciated.

Pearlduck? Pearl Dry ? the resemblance is striking!
The discoloration of the blade could be the start of cell rot?

Looks like someone played with the name to fool you into thinking they are the same. However, no relationship.
