When I took the pictures of that trouser I began to wonder if it is perhaps not a motorcycle trouser but a flight trouser! It is made of heavy but soft leather (goatskin ?) and they are roomy enough to wear them over your clothing!Two of the three zippers are made by Vitex and one is made by Ruhr!Perhaps it was replaced.The snap buttons are made by Achille Raymond.Any Informations?
…and here it is!The information I was waiting for so long!
This is a pair of French flying pants from WW2!
Many thanks to ARNAUD B. from France!!!
