Photographs with fire-brigade helmets with decal were published in the magazine:
Deutscher Feuerschutz. I do not know the number, but the year must have been 1941.
The on post 9 shown photograph was also shown in:
Hitler-Jugend im Feuerschutz. This was published in 1941 by the
Amt fĂĽr freiwillige Feuerwehren beim Chef der Ordnungspolizei, upon an agreement with the RJF.
It appeared in
Deutscher Feuerschutz, Nr. 20 from October 1940. In the booklet with about 43 pages helmets were shown without decals, the regular fire-brigade decals
and other decals. For the HY special trucks were developed, which were somewhat smaller in size.
This one and also some others were shown in
Jugend im Feuerwehr-Einsatz, 1939-1945, published by EFB-Verlag, in which the photographs from October 1941 also were
included. The same photograph was also shown in
Jugendfeuerwehren in Deutschland, a
book written by my friend Benno Ladwig (from 1963 through 1976 he was the
Generalsekretär des Deutschen Feuerwehrverbandes), published in 1986 and also by the EFB-Verlag. In my handbook I used a close-up from the photo on page 395.
Many years ago, I think about 10-15 years, the decals were shown in a cataloque from a Belgium dealer, who only sold fakes/reproductions.
