One of the rarest Soviet lamps.

A tested, matched pair is on sale.

12M1M is the first domestic low-voltage lamp.  It was developed in 1939 in the laboratory of St. Petersburg "Svetlana" by designers S.A. Zusmanovsky, S.M. Moshkovich and Ya.A. Katsman. However, the lamp was produced for an extremely short time, until about the middle of 1944, and in small series, then it was replaced (with the processing of the equipment) by 13P1S.
