M42 canteen marked RFI 43

Beautiful M42 canteen in untouched condition, the press studs are a bit rusty thereby we didn’t’t open it. The cup is nicely marked RFI 43 which indicates production by Rudolf Fissler KG, Idar-Oberstein in 1943. There flask itself is finished in the unusual green paint instead of the red primer! Nice untouched M42 canteen!
