Straight tan E-tool carrier marked dob 1944

Textbook late war straight E-tool carrier manufactured out of tan coloured Pressstoff in excellent, most likely unissued condition. The E-tool carrier is nicely marked dob. 1944 which indicates production by a still unidentified manufacturer. This is the first time I ever encountered this manufacturer on a tan E-tool carrier! The carrier features smooth black leather details straps. Perfect example that would be impossible to upgrade!
