i bought a lot on ebay recently and there were 5 lather catcher heads that have "sterling patented feb 18 1896" stamped on them. there is no ornate estching on the head like there normally would be. 4 of them are star and one is kaiser says either star or ksr where the blade sits. does anyone have idea what these are from? i thought it was odd that the star and the kaiser razor both have the same stamp. so my questions are ahy are there no etching? why do the star and kaiser heads both have the same stamp? and the little knobs that are in some of the heads seem odd as well. they are just smooth short knobs and thats it. any info would be great. thanks guys
