Excelsior Shear Co.?

I have been meaning to ask if anyone has heard of this one for awhile now. It is an Excelsior Shear Co. razor. Kind of hard to tell from the photos, but there are a few spots where the grind marks aren't consistent and some are farther up(deeper) into the spine. Seems like poor quality control for grind marks like that. Still have to hone it up and see how it will shave and hold its edge. The scales aren't original I made them.
