Checking information from an April 1939 pricelist for the HJ-Dienststellen,
along with the prices with this flyer, contrary what I found in the
Mitteilungsblatt der RZM (which was not much): this flyer must be even later
then May 1942. Probably even 1943.
In the April 1939 price-list all prices are much lower then mentioned with the flyer.
For example:
April 1939: Halstuch 0,55
Flyer: Halstuch 0,85
Mbl.RZM: Halstuch 0,75 (May 1942)
Hope this may give an idea about time. Anyway mid-war!!
