Looking for tea cups and stuff

Hi,
first of all: I hope, it is ok/the right place to post mobeyhing like that.

My mom (born in Poland in the 60s) owns a set of tea cups and other matching stuff like that in the picures. Can anyone give me some infos about it (manufacturer, what else is in the set etc.)?
We have cups, saucers, teapot, milk can, and a sugarpot.

Thank you all!
