Luster ware TeaPot

I Was told that this is something called Luster wear. Made for people who could not afford fine Silver tea sets. When I got purchased it there was a dark tarnish all over it.

I opend it up there is a white ceramic on the inside. I could not find much on lusterware  or its makers

I don't know if this is new or Old

I cannot make out the makers mark so I drew it as best I could On Microsoft paint

I would like to know its history and worth
