SPAD XIII Propeller ID?

[Larner]

Hi, all!

I've noticed this stamp on several SPAD XIII propellers, but I have yet to come across a picture close up or detailed enough to figure anything else out. Anybody have any ideas?

Hi,

The same for me: From the shape of the decal AND the one of the prop.

Approved props for SPAD XIII fitted with an Hispano 200 or 220 HP engine were (in France, alphabetic order):
- Chauvière serials 2223 and 2224,
- Éclair serials 150 and 153,
- Gallia serial 23,
- Levasseur serial 586,
- Ratmanoff serial HS and HS+ (often using SHAM construction method),
- Régy serial 361.
IHMO, the most common props surviving today are Gallia 23, Ratmanoff/SHAM HS+, Levasseur 586, Éclair 153 and Chauvière 2223 in this order. Never seen a Régy 361. The order may be different on pics.
