The canteen looks like the ww2 romanian type, enameled. It resembles the austro-hungarian ones and the cup as well as the cork are missing.
The difference was that the cup was not inserted at the bottom (like the AH ones) having the same "diameter" as the canteen's body. It stood turned over the canteen's neck, strapped with a small leather stripe.
Here is some pictures of mine. The cork is missing due to restoration. As far as I know, these canteens had no markings whatsoever. The cup is similar to the german ones, with the two folding handles.
I think that you have an imperial russian entrenching tool in those pics. Check the blade for markings...
