Difficult question to answer. Cylinders nearly horizontal, crankshaft built like a V-engine.

Puch P 800 1936. 165°-792ccm-4-cylinder-engine, 20 HP, only 550 examples produced

Some Puch P 800 engine infos (and difference between V-engine and boxer-engine):
V-engine: Two connecting rods on a common crank pin
Boxer-engine: The connecting rods of opposing cylinders are mounted on their own crankshaft throws, which are offset by 180 ° from one another

See these principles at the attached six-cylinder sketch

Please compare with the anatomy of the Puch P 800 engine

sichel

Yes, you are right, it is a Puch 800. No wonder, there are only 200 km between Vienna and Graz ;)
The description of boxer and wide-angle v-engines are very informative and will certainly make some users smarter. But there are other informations about the cylinder angle. They tells that the cylinders are raised by 16 degrees each, that makes complete 180 degrees minus 32 degrees, i.e. 158 degrees cylinder angle. But there is still something to be clarified: my main-question is: "What is shown in the picture". And that is not the complete motorbike but only a specific component. Which compnent?

Richard, You are right, it is the gear indicator of a manual gearbox. No German manufactorer. So, go on searching, good luck!
Thought you accepted this as an answer?

sichel

For double points I can be picky  ;) The Puch 800 gearbox differs in one important respect from other hand-operated motorbike gearboxes and therefore has the gear indicator.

Overdrive mechanism?

No overdrive. Locked for 'fromwien' to clear this last detail.

The four-speed gearbox was operated by means of an automatic gearshift - after the gear change, the hand lever clicked back into neutral.
The indicator on the shift linkage, prominent part of your picture, showed which gear is engaged at the moment

Yes, thats it!!! Two more points. Another interesting detail: the gearshift linkage is inserted through a hole in the main frame tube. And here another histroc photo, you like so much.
