Hi !
I got an old original 90 mm Angulon from the 50's. It is said to be convertible and there is (was) a special leaflet about it from Schneider.
I would be very delighted to get a PDF copy (or another sort of electronic form) to read.
If somebody can help me ?
TIA and have a nice day !
Note that schneider dropped the "convertibility" some time during WWII, and the 1950's Angulon is slightly different from the 1939 model: Dead Link Removed
