Period German Civilian Back Pack ostfront I am not sure if

I am not sure if these are some unusual interwar example or if they are maybe a late war example

On the black jacket

there is some wear and a very tiny chip in one corner

The material is DOM tubing for hydraulic cylinders (no seams or weak spots) so it is fairly tough but it isn't exactly proofed like a barrel would be

I know of about 4 different sizes and this will hold a 12oz coffee with plenty of room for cream or milk

Period German Civilian Back Pack ostfront I am not sure ifPeriod German back pack. It is in used but still quite good condition. There are some stains. This is a very standard and timeless type of German rucksack. A great item for many impressions, especially German civilian impression or anything German home front or what a soldier might show up with when he was conscripted.
