just bought this battledress >>but need help on makers mark , sorry about the photos but all i have at this time
the email i have from the seller
The Jacket (blouse) belonged to my father a Mikolai (Nicholas) Erfurt who was captured by the Germans in Katowice in 1939. He was then sent to North Africa where he and his friends escaped to join the British lines. He then made his way North as part of the tank corp and was demobbed in Strensall, York.
It was there that he met the husband of my Godmother to be, namely a Leon Kwiatkowski. The tunic; which is very small belonged to Leon. For some reason he gave this blouse to my father before I was born (1951). My mother is still alive (aged 92) and said that dad had always had the blouse; hence the reference to WW2. It is very small and would be circa size 8 - 10 if it were for a female.
There are no tags on the inside but there is a stamping on the inside of the left breast pocket; the attached photo refers. You can make out Blouse Battle and then some numbering.Attachment 1109346Attachment 1109347Attachment 1109348
