I wouldn't be critical for anything in the world, but I would like to point one thing out about the rifle that is in error that very few would notice ...the Masonic Square and Compass, righthand side of the stock just foward of the buttplate.
The rifle represents one that is from the period of the RevWar, 3rd quarter of the 18th century. The Masonic Symbol as shown did not come into existance until 1832, and even then only in England when the English Grand Lodge adopted the Symbol as it is shown. It was a number of years later, and even then slowly, adopted by Masonic Lodges in the United States. So.....given that the Freemasons go far back in time, what Symbol would have been correct for the time period of this rifle?
The Square and Compass would have been correct, but without the "G" in the center. (The "G" denotes "Geometry" and not "God" as almost everyone thinks, including many Freemasons). Also, the right side of the Square would have been positioned over the right leg of the Compass. That is, the right leg of the Compass would have been under the right leg of the "V" formed by the Square. The left leg of the Compass goes over the left leg of the Square as shown. Very minor point, but wanted to point it out anyway.
