The gun was found at Church Rocks, Teignmouth, Devon with XIX.319 and 320, fully loaded with stone ball and powder by the Burtons. The wreck is thought to be that of a Venetian Galley (Country Life, April 1, 1982, p.889).
It appears to be a 'Musquito de Braga' or 'Petriero a Braga', the Venetian term for a breech-loading swivel gun. In a General Treatise of Artillery by Tonaso Moretti (translated by Sir Jonas Moore, London 1683) the author describes the Petriero a Braga as follows:
The 'Petrieros a Braga' have their Chambers separated, is called the 'Mascolo, Servitore and Corvetta', and so they are loaded behind; they are serviceable upon Gallies, Vessels, Towers, and so other narrow places, where the Peece cannot reverse; they are either of beaten iron or brass, also the 'Servitory' or 'Mascoli'; the 'Braga' is of iron. They carry a ball of stone from 2 to 14L and no more....Betwixt the trunnions and the end in the middle, are place two Wings, for fasten the 'Braga' for every 'Petriero de Braga' their should be three 'Mascole'. The 'Braga' is of iron, fastened straight to the wings. It is prolonged within that it may be capable of the length of the 'Mascolo' and its Coine (chain) behind, which makes it firm; and in the end hath a long trail or train, with its button or pommel and serves the manage the 'Petriero': cross the 'Braga' underneath is a place to sustain the 'Mascolo'. The Wedge is of iron (p.37.8).
The 'Petrieroes de Braga' carry the same charge as the others. The powder is put into the 'Mascolo' or chambers and is closely shut up with a Tampion and a shot put into the chase with a wadd before and behind and the 'Mascolo' is fitted into the 'Braga' and closed with a coin or iron behind.(p.70).
Fig 8 is a drawing of A brass basis or 'Peterira a Braga' which corresponds closely with XIX.318 down to the shape of the chained wedge.
In all, three swivel guns, two minions and one saker were found. The swivel guns are identical to each other and the other three are all marked SA, suggesting they were made by the Alberghetti gunfounders of Venice. At present one of the other swivel guns is in the Teignmouth Museum, Devon. Other stone shot of this calibre has also been found.
J.R. Hale in 'Men and Warfare': The fighting potential of sixteenth century Venetia Galley's in 'War and Society. A Yearbook of Military History', ed B Bond, 1975, lists the different weapons aboard Light and Great Gallerys of the Venetian Republic from 1570 1603. The lists for Light Gallery's of 1570 includes 36 muskets ' de Braga' although later lists (with Periers substituted for muskets) they are reduced to between 14 and 18. He also mentions contemporary debate over the substitution of breechloaders for muzzleloaders because the gave the gunners less occasion for exposing themselves to enemy fire, (pp.5-6).
