Hi All,
War merit cross 1st class without swords, had it for years and bought it for a few pounds at boot sale never known what to make of it? it has no maker mark, the frosting has tarnished over the years and the swastika has always had a burnished/polished finish to it. My photos don't quite capture the depth of the stippling/dot pattern but hope they give a good idea of the look of this cross. Opinions welcome as I would like to know if it belongs with my repro collection or is it original?
Many thanks, Andy.
