Very rare,Very Early hand made copper ship's fastening or spike. Could date from the time of Columbus up to late 1700's, quite likely is Spanish. Definately hand made, crude in appearance, but has very sharp point and is distorted from hammering at head. The USS Constitution had copper spikes made in Paul Revere's factory, Nelson era English would have used early machine made spikes, so by 1800, only small shipyards would have used hand made spikes. Ships like GIL BLAS (see my other ad), as the industrial revolution began used machine made spikes more important, they were of bronze or similar alloy, NOT copper. This is approximately 8 1/2inches long. It was given to me by a marine geologist who said he found it near Anegada in the West Indies; but since I do Not know where it was made, I will put US on the customs form, if you are overseas..When a new ship was built, the butt end of the plank normally had 2 spikes driven diagonally into the frames.Between ends, 2 wooden pins or tree nails or trunnels were driven diagonally. as the ship aged and fastenings worked or loosened 2 more trunnels would be driven diagonally, as at corners of an X between ends, 2 spikes driven the same at butt ends. At perhaps 20 years old a 5th metal fastening would have been driven in the center of the X, meaning the ship was near the end of its' life, as there was no more frame space to drive pins or trunnels into. Holes were drilled with an auger, and the PINSETTER was a skilled shipright, responsible for the long life of the ship.Please see my other ad for a Slick or shipbuilding tool, which was used to shape new planks, or cut off wooden trunnels.
