Re: Georges Sablier info needed
I've had a go at Georges Sablier designation and tried to find any number sequence for Vizcaína Aviación. As far as I can tell, Sablier was contracted to produced designs (of all sizes) for potential production by Aviación Vizcaína SA but not specifically for this Basque firm.

Similar to Maveric's snip, one pamphlet lists Georges Sablier as "Directeur technique del la Vizcaína Aviación et des ateliers d'aviation de Garay y Sesúmaga Baracaldo (Retuerto) Vizcaya-Espagne". That makes it sound as if Sablier was chief technical officer for both Basque companies.
The Vizcaína Aviación seems to have sprung from the Sociedad Vizcaina de Aviación which was responsible for creating Sondika aerodrome (Bilbao's airport). I'm less clear on the connection with Garay y Sesúmaga. The Kadagua river divides Bilboa from the neighbouring city of Barakaldo and Garay y Sesúmaga was headquartered in the Retuerta area of Barakaldo.
Garay y Sesúmaga's business was primarily in rubber (Fábrica de gomas). By the 1930s, the firm was under the founder's son, José Maria de Garay y Sesúmaga (who also exploited his US oil industry background with exploratory wells in the Basque country).
There seems to be little remaining trace of Vizcaína Aviación. Nor is it clear to me whether Vizcaína Aviación was part of Garay y Sesúmaga or whether that Barakaldo firm had started its own aviation division. If the latter, Georges Sablier was indeed contracted for designs to two Basque companies.
Perhaps a Basque- or Spanish-speaking member can find more?
