WWI-period (ie. 'Preussen'-related), copper- (ie. nickle-crome-) based, EM/NCO-type belt-buckle being a moderately used example

This is an attractive - and I deem just moderately used- ie. worn! - example of a WWI-period, golden-toned- and/or typical copper- (ie. partly nickle-chrome-based), 'Preussen'-related belt-buckle (ie. 'Koppelschloss für Unteroffiziere u. Mannschaften') that shows the typical (and separately-attached) front-plate depicting a crown and text: 'Gott mit Uns' and that comes in a moderately used and/or overall nicely preserved, condition. The neat buckle - that in my opinion is of a quite early production and that can be dated around 1915 - truly retains all of its somewhat 'shiny'-styled, golden-coloured finish without showing any defaults: it was never cleaned and is just a tiny bit dirty ie. stained (as can be seen on the pictures). The inside of the buckle only shows some dust caused by over more than 100 years of storage only. The buckle itself is unmarked (something that is more often observed) as can be noticed on the pictures). The neat piece was recently found at a private-household in Germany and was never before part of a collection. Simply an attractive, WWI-period-example that is priced according to its used albeit still overall nicely preserved, condition!
