Produced sometime in the late '40s to mid-'50s, most likely. As far as the reference is concerned, we would need to see clear photos of the inside of the case back and movement.
Tony is absolutely right that nothing can be determined until we see pictures of the movement and inside the case back, including serial numbers. Although I'm sure several collectors here know what its trying to be, I hestitate to suggest a model Reference on the basis of your photo as there are many fakes and frankens in this style.
That would concern me a little in terms of authenticity. But the only way we can try and provide an opinion is for you to provide more information.
I posted this in April, and believe it still applies to anybody looking to check the authenticity of a VC timepiece.
Thanks. Dean, that was part of my original thought when I posted it. But I didn't see much feedback, so held off.
