Gdr , MI 336 - Please Help Determine Type.

Hello !
Can someone please, help me determine, from what type of Mi 336 ,GDR is the stamp on the photo?

It is difficult to identify it (watermark, paper and different colors)
Are you sure it is Mi 336 and not Mi 223 (1948, Soviet Zone)?
If it is Mi 336, I found on "philaseiten.de" a very good example for the type of paper.



LEFT ordinary paper: - gewohnliches – "z" papier
rougher surface, paper is matt, colors not so good
RIGHT coated paper: -gestrichenes – "v" papier
smoother surface, paper shines in backlight, colors are clearer


For color, maybe the picture from the Michel Color Guide is helpful:
a = dunkelrotlila
b = lila

Hello cupram

Tank you for the information. I'm also not very sure, but l tink it's Mi 336. The images you have added are very useful ,for comparison with my stamp. I will look the stamp closer in order to establish, from which type is it.
