ENGINE EXPERTS WANTED!
I (maybe) figured out how to reduce pictures (thanks to Langdon!

and was wondering if any of you engine "experts" have seen this "long-nose" version of the front prop hub installed on my 160HP Gnome 9N rotary. I know it accommodates a third, front engine mount vs the standard two engine mount of the "short-nose" prop hub version (Nieuport 28).
What airplane type was mine used on, with it's third engine mount and longer prop hub? I want to convert it to a "short-nose" version for a Fokker Dr.I reproduction, so if anyone has a spare, I would like to hear from you.
Regards, Gary
