I recently secured what was described to me as being a vintage '30s Dorko no. 856 in 15/16+. This thing is (almost) exactly like the newer no. 856s ('50's-'60s?) that have been floating around for the last ~year. My newer (50s) one is one of my best shavers - at least for the qualities that I like in a razor. I did a preliminary light cleaning of the vintage Dorko and honed her up to one of the sharpest, most stable, and most comfortable edges I've seen in a razor yet. It is like WOWIE!!!
Viva la old steel!
BTW - this razor was actually stolen upon delivery to me and recovered a month later in the unopened box!
