I am certainly no Case expert, but in looking at the pictures both blades have been cleaned and polished, but the pen blade has more pitting. Between that and the look of the pivot pin, I believe that one or both blades have been replaced.
While that might kill any collector value, it is not necessarily a bad thing. The knife may have all authentic parts (except the scales), just have been repaired. On the other hand, it may be cobbled from a variety of parts from different eras. A good Case guy could tell a lot more with the knife in hand.
Still, if the price were right, I would buy it.
I cannot help with it's gender issues, however, without a spey blade.
Jesus is life.
Everything else is just a hobby.
