don't off-hand recognize the lamp, and would tend to agree with Robert's suggestion of the word FOREIGN.
As for age, it might help if you can see the type of wiring and lamp holder - these might give a clue as to whether modern or pre 1950, although could well not be the original parts anyway.
Such lamps were fashionable in the 1930 - 40 period, although I suppose they may well have been made since. Always possible this example might be from Czechoslovakia.
