I found a Crown and Castle 13/16 "ESCO" for $20 at an antique store today. The blade is rust free with a little bit of black patina on the tang and it has bone scales that need a little cleaning.
I will post some pics as soon as I get to my camera. It says Made and Ground in Germany. On the blade is etched "ESCO" and under that is REAL GERMAN HOLLOW GROUND". I an unable to find any info on this razor so I an calling out to those that know.
Any help would be appriciated.
Thanks
Greg
