Hello!This postwar flask, 1960s, so say the Bulgarian collectors on Bulgarian forums.
Thank You , Please feel free to contact me any time with suggestions and comments Mike
Hello, MikeBulgarian colleague said to me so:"Around 1960, with the aim of replacing the old aluminum flask ( model late 1930's ) in a cloth pouch, it began production of a new "wooden" model, in the case of the coated veneer and epoxy resin. Complete replacement of the jars was never reached, so until the end of the 1990s, parallel to the model used and the old and new type".
Thanks Again , as soon I will rewrite the post on Bulgarian canteens with more detailed infoMike
