Trademark dates are not always indicative of the actual age of the razor, merely the trademark. This razor likely falls between 1890-1906 (post-1890, imports were required to stamp country of origin.) John S. Holler & Co. was a New York City wholesaler & distributor of cutlery, knives, and razors. Nice razors. The tower was their trademarked brand name.
I am no expert or collector, but I know a special blade when I see one. Amazingly Intricate! Have @HolyRollah and @gssixgun seen this?
And you'd win with either choice. I've not had a Kevin razor in my hand, but the posts by others about his work stand alone as a testament to his great skill. I've used @gssixgun, and recommend without hesitation. Hit the web page on his profile.
Works of art…and a rarity! That's the type of blade I'd keep off the hones and in a shadow box….but thats just me!
I'm always on the look out for Tally Ho razors from Frederick Fenney and came across this image of a beauty (this is NOT my razor )….wowsers!
