just because a modern day cigarette does,nt fit into the case,does not mean that it is,nt a cigarette case,...cigarettes, were smaller,when this case was made,..personally, i,d say it was a card case,....as to its value,..well, we will assume that its silver,what is its weight,..in oz & gr,...knowing for sure who made it would be a great advantage, but...all is not lost if you can,t...because when you come to advertise it,..you just need good pics of the marks,..the weight,...and any potential buyers will make up their own mind....for its not up to you to prove who made it,its up to the buyers to decide if the want it for what it is, ..or for its intrinsic value...
