Went and looked up New York and found they are little "Different". They do follow the federal guidelines for ownership and transfer.
But while you would not need a license to own, transfer or fire a antique long gun, if you want to fire your unregulated antique handgun you would need a permit.
Antiques and Replicas:
Antique rifles, shotguns and handguns, and replicas thereof, generally are exempt from the above restrictions and can be bought and possessed without a permit. (Persons who shoot muzzle loading handguns must be properly licensed.) Antique handguns must be unloaded and possessed without the materials to load same.
