Original 1 liter medical canteen with R.B.Nr. rather than a makers mark. No date. The canteen, cover and leather are all in pretty good condition. The cover has a little staining/discoloration, but no holes that I can see. The bottle has a few dents. The leather seems fairly solid and is complete. I would not put a great deal of stain on the leather. I would still consider this more of a collectors piece rather than a reenactment canteen.
