deutschmann ball from the 90s

[marci]

hallo guys,
I' m searching informations about a deutschmann ball made in the first middle of the 90s :
1) farbe = black/ dark grey /anthrazit
2) G = heavy ball ( circa 70- 80 gr. , like a 085 )
3) S = 50-60 cm.
4) H = soft as a 087 ( around 35 ? )
5) Durchmesser = circa 39 mm.
the ball was very " temperaturem-findlich " and was proposed in :
a) MR with a red-stempel of the club ( Uerdingen ??? )
b) ML with a transparent paint and the red-stempel
I also remember that :
a) the ball was made by a club near Bochum ( home of E.Deutschmann )
b) one of the players in the club was a very close friend of E.Deutschmann ( Hans Dieter Weber ?? )
thanks for your help !!
