Mistery part

[fausto77]

Hi there

I found this massive piece of iron in my country (Italy), and I don't know what is it.
I think that is a propeller reduction gear of an aircraft wrecked in during wwII but I'm not absolutely sure .
Please could you help me to identify it?
sorry for my bad english.... his weight is about 23 pounds.
any suggestion will be welcome

With the hollow quill of the shaft, it seems like it could be from a motor-cannoned engine, like a 600 series based engine - 601, 603 or the Alfa Romeo version of the 601 type. Could I ask if where approximately in Italy this was found?

propellers aren't my area of expertise but my first impression was also that the shaft hole was pretty large, so it probably had a cannon through the propeller. I'm not at all familiar with italian aircraft but the american p-39 had a cannon but i don't recall any fighting in that area. The americans used a lot of p-47, b-24 and the b-26 in that area but none have a cannon in the propeller. The german ME-109 had a cannon in the propeller but I don't know how heavily it was used in Italy. Good Luck

Hi,
It isn't from a 109. The main hub gear of a 109 has 54 teeth and 8 bolts. Yours has 53 and 18 bolts. This part looks heavier in fabrication than the 109 hub gear. I have attached a photo to compare. No part-no's somewhere?

Cheers,
Sander

The output shaft looks too short for a reduction gear, and it doesn't appear to have any allowance for mounting bearings.

is my two main doubts.......
I bought it from a guy in Sicily, no markings, only a number 1 embossed on it
