I agree.
Answer his questions.
I am curious about the green stuff on the pommel and in the center of the crossguard when none at all is on the crossguard ends.
Dave, to my best knowledge, this certain green verdigris is mostly a bad sign on early, nickle silver party daggers as there it is often a sign of artificial aging.
Here we have a brass navy dagger and brass often, even in relatively short time can build up such patination.
Why the pommel and parts under the wrapped portepee are concerned member Flyingdutchman has already answered in a imho proper way.
