Help needed for ID

[MSMRCK]

Hi all, I need help for identify the engine that used this air compressor:









The Company "Air Equipement" was created in 1934 in France (Bois-Colombes) and produced aircraft engines accessories



This part probabily belonged to french WWII engine maybe an Hipsano Suiza?

Thanks for the help

I'm not 100% sure but that might me a "pump" for providing either pressure or suction to the gyro instruments.

It is an air pump, early design, later ones had a spring loaded poppet valve in head, much the same as the ones used on the british engines in WWII. use engine oil for lube.

I don´t know which a/c used this compresor but for sure it is a French product.

I'm pretty sure it's either a thing or a do-hicky!

Most accessories like this were used many aircraft, same as the generator.
The british version was used on the hurricane, spitfire, lancaster and on & on.
