Hi Mario, The Gem C has decals like this and the Gem decal on the front and Edison made model B C and D's at the same time which is why you will see some home B's with the decal like the D's, Edison never wasted he used up all of his stocks. I believe it could have been a mistake. The R and S reproducer shared serial numbers as did the O and N, but I have found some of these with the wrong serial numbers such as N-56 31104 with a R&S serial number. Instead of putting the adapter on it and making it an S it became an N-56.

I'm sure all the Maroon gems I've seen had the "Edison" decal on the body.........Transition? > > Cheers,> Mario> _______________________________________________> Phono-L mailing list> Phono-L at oldcrank.org> > Phono-L Archive> http://phono-l.oldcrank.org/archive/> > Support Phono-L> http://www.cafepress.com/oldcrank
