My Sharps Repro was made in the late 1970's or early 1980's and is stamped very small on one side "Garrett Arms, Norfolk, VA" I understand a guy named Garrett took an original Sharps to Italy and had the Palmetto company run off a few thousand copies. He sold them here in the states. In fact I bought mine from Mr. Garrett himself at the Baltimore Antique Arms show.
I have one Palmetto that was a kit, and the description, "in the rough" would be kind. The finished guns I have purchased have all been very good. There was indeed some unbelieveable junk on the market in the 1970's. Ultra-High, Markham Arms, and some others. F. W. Woolworth and Woolco stores sold some of the worst of the worst. As in other firearms from Italy, there was the amount of fit and finish and quality control the wholesale customer wanted. The Italians were known to sell anything and everything from paper weight guns to quality, and all off the same production line. Now, would an italian made revolver ever match the smooth operation of a Ruger Old Army, probably not without serious aftermarket tuning.
