I'm not an expert, but should be a SM 55 propeller? Many years ago i seen a very similar propeller in Vigna di Valle Museum (Italy), but two pieces formed. It was Italo Balbo's Savoia Marchetti SM 55 (1936).

The my propeller is 4 pieces formed, while the S.M. Italo Balbo's was two/three pieces propellers formed. I'm not schure it's S. M. 55 propeller.

What do you think about?

Ahem... sorry for my horrible language I don't speak very well, there will be many errors :oops:

Nice job posting the pictures!

I would say by the way it was cut at the hub that it was most likely one blade from a 4-blade combination. The original diameter of the whole propeller was 2700 cm. Also, the serial number, the brass leading edges and the use of a "Heine" decal all suggest a production after WW1, so that would be at least consistent with the time frame you suggest as well. It was not unusual for many aircraft to have experimented and used two-blade and four-blade propellers.

I don't know what the "L5" stamping means.

Ok thanks Dave, I have measured a single blade and it corresponds to 135 cm for a total length of the propeller therefore of 270 cm around, I'm right to believe the propeller is really of that epoch. What "Heine" means? Was it the factory? Was a Germany production?

Dave 02-28-2006 03:16 PM

Heine was a very well know German propeller maker in WW1, and probably well before the war as well, and they continued to manufacture them well after WW1 also (unlike many other manufacturers). I'm not sure that there may still be a subsidiary of that company still in business today.



Here's a link to one of their earlier propellers, http://www.woodenpropeller.com/Heine.html
