Vintage/Antique Vaudoscope Need more info

I purchased this penny arcade game hoping to find out more about it. The only thing so far I can find is that it is a Peerless Co. penny vaudoscope rather a mutoscope. In the vaudoscope you get to see about 6 still pictures flip by for your penny (rather than the moving pics in a mutoscope). It is electric and has all amber tone and Black /White "girlie" cards and some look to be postcards. It does work and we had a key made for it by a locksmith that believes it is an English lock. Can anybody help me with more info? I'd love to know its age and possible value. Thanks!
