Come on, England and Holland weren't the only countries to make big six cylinder engines, keep on trying.

[targhediferro]

Fiat?

[ropat53]

Not FIAT but you're getting closer

[4popoid]

How about a Diatto (or Diatto-Clement) from about 1908?

[ropat53]

Not Diatto-Clément, but the right countries.

[4popoid]

?

Your previous answer says "Not Diatto-Clément, but the right countries."
Now, Aquila Italiana were from Torino  and  Diatto or Diatto-Clément also came from Torino.  So, are you saying that this manufacturer is Italian but not from Torino?

[targhediferro]

You say...right countries!  Is this engine Italian-French?

[4popoid]

Florentia (licensee of Rochet-Schneider) from about 1907?

[ropat53]

You say...right countries!  Is this engine Italian-French?

Yes these two countries are involved, but in different order.

Not Florentia (licensee of Rochet-Schneider)

Well if I understand where this puzzle is going, it appears that we are looking for a French 6 cyl. engine, and possibly a French marque, but with some sort of Italian connection.  Therefore, let's try this scenario: In 1907 De Dietrich purchased Isotta-Fraschini, who produced chassis into which De Dietrich installed their engines, for sale as De Dietrichs.  In 1908 De Dietrich produced a six cylinder 70/80 HP engine.  I don't know if this engine was ever placed in a Isotta-Fraschini chassis, nor can I find a picture if the De Dietrich 6 cylinder, but on the chance that this might be the correct answer, I'll guess that the puzzle engine is a 1908 De Dietrich 6 cylinder 70/80 HP.

[ropat53]

It's not de Dietrich and Isotta Fraschini, but your on the right track.
One more hint it's French but made in Italy.

Welleyes-Ceirano 1905?
