Geneva Cutlery Co

So I have 8 razors with a wide price range from nothing to several hundred dollars. My best razor is my Geneva Cutlery razor that I won from the monthly giveaway here (which by the way I haven't seen the last couple months it seems). It takes a buttery smooth edge that passes every "test" with ease from tnt to shave test. I know that Geneva Cutlery is also Genco. What I am curious about is whether or not their quality was consistent through out the companies existence I really want to know if I can expect that level of quality from a razor made in 1902 and a razor made in 1970. I know that they were a reputable razor maker just don't know if there quality ever slacked off or was better at one point than another.

Genco's razor division went to Case in 1935. The side of the company making and selling other items continued seperately.
Case and Genco were made alongside one another at the Bradford, PA plant for a while. No Genco razors postwar.
I never saw a Genco/Geneva, in good condition, which was not very good!
