Im not having much luck finding info on this particular razor.

I recently inherited an old dubl duck satin baby in fair condition. the only problem with it is that the blades all rusted up and needs a good thorough refinishing. the scales are also in good shape with general aging. and a green patina on the metal fittings. although I don't know much about using straights yet I would love to find out some info on this particular razor. any help would be apprecitated.
