Helice Normale

[Dave]

Hi Pierre-Michel,

I just now found numbers on it that I hadn't seen before, stamped just adjacent to the hub impression. They are B-78 then a space and then 843. I'm going to take it down and look more closely for other markings.

Do those numbers mean anything to you? I presume the 78 reflects the length of 7" 8", although I wasn't even aware that Ratmanoff might have used inches rather than centimeters.

Hi,

I have the same remark: "logo" perpendicular to wood grain (and glue lines). The blade tip is "above" the picture I post (and hub below). It is a serial KU for Gnome engines (a/c unknown for now).

@Dave: could you tell me what are the serial of your Ratmanoff (usualy letter or letters, sometimes letter(s) + digits)?

Regards,
PM

I'd say that it's very likely that it's from a propeller, but interesting on the only Ratmanoff (Normale) propeller that I have the logo is placed perpendicular to the wood grain, where on yours it's parallel.

Thanks very much for such a quick response i am most greateful

Good Evening,

As the grandson of an aircraft designer (AC Brown B1892 ) I have been going through some of his old Fairey aviation bits and pieces and have found a block of laminated wood with the Helice Normale motif on it. I would be grateful if anyone can tell me if this was made from a prop and if so any more information. I will try to load a couple of pics to make life easier.

I thank you all in anticipation of your help

Regards
