Not at all , it is a very common Sida camera (Kraftanski work) you can see it in my wooden box maliutka / lilliput collection i show you some times ago.
No I am not planning to buy Sida yet. As I remember I use to collect Russian cameras But I was surprised to know the origin of Liliput and Malutka. I was thinking they was completely Russian creation. I was wrong
you must read something about Fritz Kaftanski strange life ....something like a stateless ingeneer, whith built cameras in poland, Tchekoslovaquia, France , germany...may be England.
