Missing cap. There is nowhere on the bottle that says what scent this is, but it looks identical to Egyptian musk as far as color goes, and I did give it a spray and it seems like it could smell like that (I'm not familiar with the original scent).
This is a vintage perfume. Although it has been stored carefully, any and all perfumes can change/turn scent over the years. As well, different lots manufactured at different times can smell different because the company changes the formulation. Therefore, this may not smell the same as one you currently have or as you remember.
