LeFusil, I'm not doubting what you say at all but did the maker in question publish any of his findings ? I'd always been under the impression that rust blue was more durable but always have an open mind. I've seen the tests done to firearms for the military grades of rust protection and wonder if these are similar to what he subjected the parts to.
Coincidently, I've found that blood can remove some blueing pretty quickly .
