M42 canteen marked KVU 44

Textbook late war M42 canteen in very good condition. The canteen is a typical late war example with a rough wool cover and mixed pebbled and smooth leather on the straps. The green painted flask is nicely marked kvu which is the late war replacement for RFI which indicates production by Rudolf Fissler KG, Idar-Oberstein in 1944. The cup is matching to the canteen and nicely marked RFI 43 which indicates its most probable production very early in 1944. The canteen is in unissued condition and would be very hard to upgrade!
