Rare large canteen marked RB0/0570/0038 with gaberdine cover

Possibly one of the rarest canteens! A one liter large Labeflasche as issued to Gebirgsjäger and Sanitäter. This late war variant is marked RB0/0570/0038 on the canteen and comes with a gaberdine cover. The canteen and its cover are in good used condition. The strap is supple and undamaged. The gaberdine cover is super rare and only scarcely encountered on large canteens, the first one I have ever found!
