Iron Cross 2nd Class 1939 in Envelope, Paul Meybauer Berlin SW68

In a very good, probably unworn condition. The core with practically all of the black paint still present. The ribbing in matt silver, the flanges burnished and all with some slight patina. Still in the original tissue paper wrapper. Three piece construction and magnetic.
Not marked but a known variation that has been attributed to the company of Paul Meybauer, Berlin (7,L/13). With long unused ribbon.
The fitting small blue envelope, apart from being torn open along one side, in a good, used condition. Printed on the obverse with the designation and on the reverse with the maker „Paul Meybauer Berlin SW68“.
Very difficult to find set.
