Hi,
Gerolf Poetschke, who is maintaining a website for German pre-war tv sets, has made a trip to Russia. He visited the Popov Museum of communication in St. Petersburg. Several Russian prewar sets and cameras are on display:

Additional, he made some photos of early Russian colour TV, and with them the first Russian color tv set from 1954, the Raduga:
