Beautiful bastard chair. Anyone know the designer??

So, I'm doing tons and tons of research and not turning anything up on this chair! It could quite possibly be something nice from the 1950s that was mass produced without any credible designer.. but if you look closely it's really well fabricated, and the X base is.. well.. Eames? Right? If anyone has any ideas please shoot me an email! I'd love to find out more about this chair!
