Hi AS a newbie to the forum I need a little help and hope this is the right place. I have purchased 2 props recently and need some help identifying them :
I will add details of the second prop later but the first I believe could be an SE5 prop ?
See pics added
Any help appreciated

Newbie myself who just identified a propeller. Getting measured dimensions a big help identifying. Look at the "propeller identification early propeller section" and get the hub dimensions. Then length. Helps the more seasoned members/fellows out quite a bit.

The "DG 2386" presumably is the "Drawing Number" of 2386, which is usually the way the prop is identified, but I can't seem to find reference to that number in my sources. Bob Gardner or Pierre-Michel might have some other source that would help.

What's on the other side of the hub? The information seems scant by comparison to most similar props.

Hi,

It's clearly a Chauvière made in England. With a very well preserved decal: take care of it!
Chauvière serial numbers were different in England and France. I think Bob will be delighted to see this prop because, IMHO, this serial (2386) is not in his book... So, as gchuba wrote, length, hub thickness, size of the central hole and diameter of the bolt holes circle will be very useful.

From the general shape, it is a "late" production (1918-1921).

Regards,
Pierre-Michel

410cm= 13ft 5.417323in

That doesn't seem at all consistent with the photo. Did you mean 310 cm?

This small forum has never been accused of being lightning fast, and two of the most helpful experts, Bob Garner and pmdec, don't check in every day or even in some cases every week or so.

I don't have any new information based on the length except that it makes more sense and some props can be eliminated as possibilities but positive identification requires making sense of the blueprint number ("DG" number of 2386).

Hi,

I can't add anything useful: 2386 is not a known serial (drawing) in France for Chauvière (or for any maker of the WW1 era).The size (2.40 meter) is quite common: there are 14 different French made propellers with a diameter between 2.35 and 2.45 meters and used for Hispano engine. From these 14, none have a 13.3 cm thick hub. French hubs fitting sizes were standardized to 4 patterns (A, B, C and ... D, yes!) and none have the numbers you wrote.

Sorry not being able to help,
Regards,

Is it possible to ask bob Gardner to have a look at this prop as it's an English prop ? Not sure how to ask his help ?
Thanks

It is an Integral Propeller Company prop made in Great Britain to a Levasseur design for the 150hp Hispano-Suiza engine in the SPAD 7.

With kind regards,

Bob
