Strange Yugoslavian canteen

I figured I would make this video to ask the community a question and that question is what is this canteen. Is very similar to the standard Yugoslav/Serbian canteen with the late only being some minor changes in looks really the most obvious it’s orange feather then green and the small cup is translucent rather then solid colored. I really hope you guys can answer this question for as I have not seen another one like this even though I have owned this canteen for years. Hopefully you liked this video and subscribed if you like this sort of stuff. Please leave a comment with any questions, additional information, or suggestions for future videos and I will do my best to answer them. As always thanks for watching. Thank you, Devin K.
