There were 975 sets of these produced starting back in 1976 under the auspicies of the U.S. Bi-Centential Society that morphed into the U.S. Historical Society after 1976. Those two Societies basically existed to have historical artifacts, mostly firearms, exactly duplicated to a very high standard and marketed ,as a potential investment, to the wealthy who had more money than sense. This set was initially offered in 1976 for $2500 and raised to $3000 after the initial subsrciption. In todays dollars that is around $15,000. Of course all of the issues turned out to be terrible investments. However since all of the various issues, all made by Uberti, were made to such a high standard at the prices they bring today they are a real bargain. The originals that this set replicates were made by the London firm of Richards and Hawkins in about 1746 and gifted to George Washington in 1778 by a neighbor. They now reside in the West Point museum. This set, like the originals, are .58cal bronze barrelled smooth bore, sterling silver mounted, in French walnut stocks. The locks have half cock safties and water proof pans and throw a scary amount of sparks. The original markings and engraving are also present. I had to order some supplies from Track and as soon as they come in I'm off to the range. Can't wait to see if these shoot as good as they look.
