Hi, I found this small teapot and I tried to idetify origin, but without much luck. It has two headed eagle in rhomb (I guess it's mark for country, but I didn't find any similar) and below it has four squares containing letters "W', "&", "G" and "crossed hammers". The number "145" is also on inside of lid.
Any help is appreciated.
