Prop clock ID req'd, please

[Bravo1]

Hi all,

With reference to the pictures below of a SPAD propeller boss, can anyone tell me if the clock is actually from a SPAD or not? Also how do you change the time on it and wind it up? There are no keyholes or keys visible. I would hazard a guess that to wind it up, you would turn the knurled bezel around the edge of the face (there is a directional arrow on the front of it) and to change the time I suppose that the glass cover could be removed and the hands moved physically, who knows? I'm certainly open to suggestions! Incidently, the following is stamped on to the boss itself:

SPAD F XI

HISP 150

I look forward to your thoughts on this!

Bravo,

It is as you suggest a rim wind clock which dates it to the WW1 period and a little later. It was used on automobiles and aircraft.

With kind regards,

Bob

Hi Bob,

Thanks for the reply, I assume that the hands have to be set from the front so have you any idea how to do this?
