Default Helice Levasseur prop

Dear Forum,

I own a prop with the above name on it and I would like to find what aircraft this would have been used on and how old the prop is. I have pictures if needed.

Biggles,

We need photographs and details of any data stamped on the prop. If they are not clear to read, include a macro photo of them.

With kind regards,

Ginger (aka Bob)

There should also be numbers stamped on it, the most important being "Serie xxxx", which can usually be cross-referenced.

That's weird. Something doesn't seem quite right. It's not the usual Levasseur design, which typically had a flat leading edge and a curved trailing edge, similar to this one. It's also unusual in my opinion to see a French manufacturer not include a "Serie" number stamped on the hub. I don't recall any Levasseur propellers using the word "pitch" either. It looks as if it's either been refinished or even recently constructed, and there is no evidence of its actual mounting on a hub for use. Except for the decals, it almost looks "too perfect" for a prop that should be nearly 100 years old.

Maybe PMDec will have some input, but for me right now it's a complete mystery. (Didn't Levasseur propellers usually have a coating of dark paint rather than clear varnish?)

I suspect it may have been mercilessly refurbished but it might be a fake. In its favour the Levasseur decal looks to be original. The layout and construction of the laminations look correct. The overall look of the complete propeller is British; olive green fabric on the tips. Early purchases by the British of 150hp Hisso engines were used in the SPAD. One of several props used was AB764 with D2414 and P1850 and stamped Levasseur Design.

With kind regards,

Bob

AB723 for the SPAD also looks like Levasseur design, but I wouldn't expect to see Levasseur decals on a prop made by a different manufacturer.

I know you can't tell much about accurate colors and manufacturers did change them, but even then the decal looks a little "bright" to me. Compare it to this one, which is from a cut section of a propeller, and runs transversely across the blade instead of along its length.









I just haven't seen and/or photographed enough Levasseur decals to know if this one is "normal" or not.
