Thread: "E. Guthner" razor

I recently converted my father to straight shaving and he has been stricken with a serious case of RAD. He has found some great razors, though. He found one today at an old gun store of all places. It is marked E. Guthner on one side of the tang and has the eagle and snake on the other tang. It looks very similar to the ERN eagle and snake. Anyone out there have any information on this maker? And, let me apologize in advance for the lack of razor porn. He has the razor with him. It's a 5/8 with a barbers notch. I'll try to get a picture a bit later. TIA for any info you have.
