very good cosmetic condition, with case, no power supply or cable (original connector included so you can make a cable)

Nickel membrane M62 capsule is the same as the west German Neumann KM54 capsule

works perfectly, sounds great!

From the 1950s

Uses easy to find EC92 tube.

*Gefell (in east Germany) is the name of the town where the Neumann factory was before World War II. After the war Neumann relocated in the west and continued managing the factory in Gefell from a distance. The East German communist government took over the factory sometime in the 1960s and started labeling everything RFT, which was the government name for lots of electronics products in east Germany (not all RFT products are from Neumann Gefell, the RFT name is on a lot of junk as well - RFT dynamic and crystal mics are not from Gefell). The RFT-labelled products from the Gefell factory are of the same high quality.

When East Germany collapsed and the Berlin wall came down in 1989, the Gefell mic company renamed itself Microtech and continues to make state-of-the-art mics and replacement parts. Neumann sued to get their company back in the 1990s, as did many companies whose property had been taken by the government, but I don't know what the outcome was.

The products from Gefell, whether they are labelled Neumann, RFT or Microtech, are comparable in quality to the West German Neumann products, and many of the designs are similar or identical, especially the mics from the 1950s and 1960s. They're cheaper, often selling for a small fraction of what a comparable west-Neumann mic would sell for, simply because they're not as well known.
