Late war Luftwaffe issue rucksack marked RBNr. 0/0390/0204

Excellent late war Luftwaffe issue rucksack manufactured out of multiple shades of blue fabric. The rucksack is in excellent condition without any damages at all! The rucksack is nicely marked RBNr. 0/0390/0204 which indicates production by an unknown manufacturer. Excellent rucksack in mint condition which would be very hard to upgrade!
