A Turkish neighbour of mine confirmed that it is illegal to own ex-military equipment in Turkey. Mainly to do with the Kurdish problem.
(He's in the legal department of the Turkish Consulate in Frankfurt)
The only exception are re-enactment groups, which, in Turkey, are confined to the Ottoman
period, mainly with Mehtar bands and Jannisserie groups. I don't think that the Turkish government are worried about swords, spears and bows yet!
