WWI-period 'Eisernes Kreuz 1. Klasse' being a non-converse-shaped example with the makers'-designation: 'KO'

The attractive cross - which is a typical non-vaulted (ie. non-converse-) shaped example as more often encountered - has - I deem - never been (recently) cleaned and retains a nice- (albeit minimally tarnished) age-patina and/or great pronounced detail. This WWI-period example - which is a (partly) genuine-silver-based- ie. magnetic example as more often seen - comes mounted onto its original (and naturally fully functional) straight-shaped (and somewhat longer-sized) pin and has an unaltered (and also functional) catch (as can be seen on the pictures). The cross - which shows a nicely preserved, 'blackened'- and/or fairly 'satin-like'- ie. somewhat 'matted'-like 'inner-core' - shows some minimal age but is totally void of any real damage: it retains a very nice appearance overall. The piece is as stated above showing a clear makers'-designation on its back that reads: 'KO' (as can be seen on the pictures) and can as such presumably be attributed to the maker: 'Klein & Quenzer' as based in the town of Lüdenscheid. The cross is, moreover, just a bit dirty and tarnished simply caused by years of storage and/or moderate wear but retains a great unmessed-with and/or uncleaned, age-patina. Simply an attractive IC-first-class that was never before part of a collection: I deem that I have priced this attractive WWI-period example, accordingly!
