The acronym MWD stands for Ministry of Internal Affairs of the URSS. It was used in the de-Nazification in 1946. It also carried out a tough post-war treatment with punishments and purges to the population in German territory.
The thing that does not convince me of this Distler is that the white paint used for the writing is recent. Another thing is that the same seller on ebay sells all brown paint models with red stars on them. All models done the same way. Ummm....I don't believe that painting is original of the time, I think is fake.
Thanks so much Andrea for the information !! YES, it does seem unusual that the same seller has similar toys painted with the red star and the white MWD lettering on the DISTLER looks some what new ? ? ?
