The first example is, I believe, for small tools and these have turned up from time to time in the gloveboxes of M201s from the Domaines auctions. There is a vinyl loop inside that is about the right size to hold a spare spark plug though I do not know that this is exactly what it was for.

The second example is of a 'porte-documents' belonging to Michel Alezard (M201 No. 23193) who provided the photos. The word 'jeep' and the remains of a yellow band of paint on the back have been preserved in original condition. The registration number is that of Michel's jeep.
