Often, on a Spanish archaeological site, used flints will be found that have become round in shape. This is due to the fact that they would rotate the flint in the jaws of the cock and continue using it until it would no longer hold in the jaws. The strong mainspring on a miquelet lock would usually make any flint spark that could be held in the jaws. A Trabuco (blunderbuss carbine with a slight muzzle swell) was found on one of the 1715 Plate Fleet wrecks that I was able to work on. It was set up for horseback use with a long sash hook on the left side. It was signed on the barrel, "Mexico", "Ramirez", and Anno 1709. Ramirez and 1709 were repeated on the back of the frizzen. 15 years later, a matching pistol was recovered miles to the north that had the swelled barrel and the same markings. James D. Lavin's book mentions two firearms in the big arms museum in Spain by the same maker that were dated 1708 and 1710 and they were both repeaters with a long magazine under the barrel (one is pictured in his book).
