Back in the mid-70's, the original CVA company built a .61 caliber pistol with a Miguelet lock with flint. The barrel was half round-half octagon and advertised as "fully rifled". The gun was also called "partially engraved", 15" overall length and 40 oz. in weight...and all for a mere $85.oo. The only one I've ever seen is on display at the Institute of American Cultures in San Antonio, used to illustrate the type of firearms used by the Spanish. Was wondering if anyone else has ever seen or owned one of these, and if so, were they really reliable shooters?
