Uzumlu is a village 5 kilometers away from Huglu village.
Both Huglu and Uzumlu villages of Central Anatolia
manufacture shotguns for 70-80 years, and they work on a
cooperative basis, every villager work for the cooperative,
one house makes the trigger part, the other makes the
receiver and so on... However, the Uzumlu cooperative
dissolved and many new family-owned companies emerged out
of it. Derya is one of them. I personally met the owner of
that company, an old and nice guy, who is in shotgun manuf.
business for at least 40 years. I visited his small atelier
and saw that every part of the shotgun is hand made, except
the barrel. Regards, Kamil from Istanbul"
