Hanquet was still in business in early 1980s. I think they carry the brand name Centaure. They imported colt. They have been in the making of a lot of different gun, handguns, reproduction of muzzle loaded exportation style ( poupou ) and in the 70s a nice reproduction of napoleonic pistol. They sold colt parts and maybe was official colt distributor. They got a lot of comblian, rollingblock Martinis... still in stock for refurbishing.It was a pleasure to see the piles of old guns , unfortunatly without market. I heard the Mlle Hanquet married the manager and the busineess closed. Happy ending.
