So far: buy recommendation
Mechanically (M42 threaded ring had to be turned approx. 15° to the right) and optically (mounting distance is correct) in order. Lenses (1.8/50mm and 2.8/135mm Pentacon electric multi coated) take sharp pictures with the Nikon Z6. However, these approx. 48-year-old glasses, although mechanically and optically completely OK, cannot be compared with today's glasses in terms of the sharpness. However, pictures look very pleasant without a direct comparison.
