Messier Liquide vert ?
Has anybody come across a Hydraulic Fluid "Messier Liquide vert" used in 1950's Hydraulic Shock struts (light aircraft) with a view to finding a modern equivalent. The description "Messier Liquide vert" comes from the drawings.
I have e-mailed Messier for advice (Both UK and France) but have had no reply plus of course Google.
Has anybody come across this fluid or a specification? My original thoughts were a 585 mineral fluid but the sample from the strut was considerably more viscous - more like a engine oil.
Some Citroens possible used this in the suspension.
Any thoughts or directions would be appreciated.
