I came back from the Soissons auction with an interesting Uberzug
We cas see the white seam which was done to reduce the size of the Uberzug. The sewing was done at the base of the each side.
The look of the Uberzug is a little strange with an acute angle.
The inner protection if the spikecover is more interesting. In the case of this Uberzug, you won't find the standard sewn leather piece but a simple sewn low quality fabric. The protection against friction is closed to zero as the material is very thin. It is a good example of the shortage of raw materiels in Germany during WWI.
The sewn piece could be done to give the impression that it was an Uberzug as the others.
