Hi Kaz,
not sure, poss Czech or Scandinavian, looks familiar, i will keep an eye out on my travels.
IMHO its quite a lot nicer than the Amber bottle.
Cheers

ps, yes , would have had a stopper, the inner neck is ground to make a good tight fit.
looks well made.
Send Lee back to find the stopper, and tell him not to come home until hes found it.
