cigarette case/lighter

:hello: Hi there I want to buy this cigarette case from a local dealer, but I don't know anything about it - he says is silver but I have my doubts ,it could be alloy or any plated. Also, anyone know what kind of year this might be and what technique used to make this ... looks like a press ...

I'm not sure of the age of this matching set but, I found this today at my grandparents old home (On a shelf in a closet). I have found some images of close resemblance but, nothing that gives a hint to the age. Any ideas?
