Another interesting engine, thank you Sichel.

A 3 cylinder 2 stroke?

sichel

Yes, it is a 3 cylinder 2stroke-engine.

3-cylinder 2-stroke - is it anything to do with Auto-Union / DKW? (the history of the two is so intertwined that it is impossible to separate them)

The more you learn, the more you realise how little you know.

sichel

No, it was a completely different company.

Was it built before 1930 ?

Yes, Bolle & Fiedler. Locked for Wendax to answer the remaining question.

Dear 'sichel', please excuse my far too early reply. Thought the puzzle has been solved, after 'Wendax' found the manufacturer. I hope such mishaps don't happen to me again

Wendax

Max Georg Fiedler designed several two-stroke engines for Bolle & Fiedler. The first three-cylinder engine developed 24 PS out of 1026 cc. Bolle & Fiedler probably also built the three-cylinder two-stroke engine for E. Rosineck (Erco, Eos) which was a 20 PS 1086 cc one. After 1925 Bolle & Fiedler built boat engines like the one on fromwien's post.

We've had a Bolle & Fiedler car before: https://www.autopuzzles.com/forum/new-board/pn-1389/

sichel

Yes, it is the 24 hp engine with 1026 cc, installed in the 1923 sports car, see: https://www.autopuzzles.com/forum/new-board/pn-1389/
One more point for Wendax.
