This piece came out of an advanced Imperial collection and was identified as a German lancer stable belt. I honestly can find this in none of my reference books nor can I find any other examples online. The construction and stitching certainly is consistent with WWI and the name Zoller is certainly Germanic so I am confident in this identification. There is a a stamp in red ink running for a few lines but is illegible due to age fading (See attached image 6). The leather shows wear but looks to be in solid shape. If anyone viewing this listing can offer more information input is most welcome.
