The Sulzer brothers founded this company around 1834 as an iron foundry factory near Winterthur.

-Around 1947 it was invited to produce an engine capable of powering the new Swiss N-20 fighter plane. It joined forces with Brown-Boveri and Escher Weyss and projects such as the D-45, DZ-45 and DK-45 and their variants were made.

The DZ-45 has a great similarity with the SM-01 that was finally manufactured by EFW in Emmen.

-Gebrüder Sulzer manufactured the DeHavilland Ghost model 48 Mk1 for the Vampires of the Swiss Air Force.

-One of these engines is on display at the NASM.

-But more interesting has been the discovery of an example of the D45, which is also mentioned in the main text, precisely the D45.04 and which we see below.
