Nice razor! No, if it is vintage, I don't think you got ripped off. I am willing to pay more for mint or new in the box or new old stock (NOS), as well as for detailed finish work, such as you have on the blade. I have never heard of Mondesir (My Desire) but it looks like a quality piece. In the end, though, it's all about the shave. Have honemeister put a finish on it and then let us know how it shaves.
