Landships II

In 1915 (or rather 1916), the Germans introduced a lighter pack consisting of the greatcoat covered by the tent section and rolled round the mess tin. This was used until well after WW1, I think at least Freikorps and Reichswehr seem to have regularly used the same arrangement.

Could anyone please tell which other troops used the same arrangement, German or other?

I am looking for conversion possibilities for 1/72 WW1 Germans. Thanks in advance, Pat
