What is this old Tudor? Real? Fake?

I suspect yours was either OWC or a very early Tudor (mid 40s) with the rose inside the shield logo. Inside of the caseback will have the name of one or the other. Lugs are unusual but ok.

Thanks very much for responding - that's helpful. I've never opened the thing, I suppose that's the next thing to do...
