(See BMW and Siemens).

Bramo engine models were preceded by the letters "Sh" from "Siemens-Halske" subsidiary of Siemens Electric Group. Some products were known as Siemens-Schukert-Werke, joining together with the former.

-The Siemens-Halske began manufacturing the Gnome Monosoupape engine around 1911, and they soon developed their first engine, the 9-cylinder, radial Sh-1 with single-valves. It was a bi-rotary engine where the cylinders rotated in one direction, and the propeller in another. It had a power output of 100 CV.

"Bramo 11 cils"

-The Sh-3 had 11 cylinders (one of the few engines with this number of cylinders in a single row). It delivered 160 hp and was bi-rotary as well.

-The Sh-3a version gave 240 CV.

-The Sh5 from 1921 was a stationary radial, and had a power output of only 77 CV. The Sh-11 with the same displacement as the Sh-5 delivered 96 CV.

-The Sh-14 from 1931 gave 115 CV while the Sh-14a version reached 160 CV.

-By 1927, Siemens acquired the Bristol Jupiter license, thus the Sh-20 and 20b engines were strongly influenced by the Jupiter engine, but they were somewhat larger, delivering 550 CV to 750 CV in different versions.

-When in 1936 the company was reorganized, it was renamed Bramo (from BRAnderburgische Motorenwerke), although very little later, in 1939, it was acquired by BMW.

-The derivative thereof was the 323, a 9-cylinder radial, nicknamed as "Fafnir".

-The so-called  "Twin Fafnir", with 14 cylinders instead of 18, was submitted to a contest of the German Air Ministry or RLM, along with other engines of other brands, but they were all swept away by the new BMW 801.

"Bramo-Fafnir 323"

-The BMW Bramo-Fafnir 323 with 1000 CV was very important in the new Luftwaffe, both for the quantity that was built and its applications, and also because their latest models reached even 1,200 CV.

From Appendix 10: As the main product they had the Sh14A4 engine, licensed by Siemens & Halske.

-They made an important range of Siemens & Halske engines in addition to the so-called "Fafnir".

-Later, in the year 1939, Bramo was acquired by BMW.
