A little background: The Ancient And Accepted Scotch Rite entered the Colonies at Charleston, SC in 1732, or very close to that date.(Could have been 1736, but I think I remember 1732 in my studies/work). Freemasonry was already in the Colonies, but was practically dormant until the F&I War. Virtually all of the British Regiments, I forget how many there were, but maybe around 20, had Regimental Lodges of Free And Accepted Masons, and this caught on very quickly with Colonial Militias. By the time of the RevWar Freemasonry was well entrenched in the Colonies. The relationships between British and American Freemasons during the RevWar is an area of history that has never been reported on to any degree. For example, King George's brother and several British admirals and generals, all Freemasons, pleaded with KG to work out a political solution and not a military one. Not many of us know that.
The Double Headed Eagle: This is the Ensign of the old Kingdom of Prussia, and Federick II, the King from 1740 'till his death in 1786, was a 33rd Degree Freemason. In fact, he was the Chief Architect in taking the finer points of the 32nd Degree and refining them into the 33rd Degree. For his role in this the Prussian Ensign was adopted as the symbol of what we now refer to as the Ancient And Accepted Scottish Rite Masonry. The symbol of the 33Degree will have the Crown that Ron mentions atop the Double Eagle Heads, and atop the Crown will be a Triangle within a Triangle, and within these will be the number "33". Without the Crown, the Symbol is referencing simply the Ancient And Accepted Scottish Rite which is made up of the Masonic Degrees four through thirty two. In both cases the talons of the Eagle will be clutching a sword with the point always to the right.
In looking at Dr. George’s RCA, #63 on page 264, the rifle made by Andrew Verner, take a close look at the Double Headed Eagle, underside just forward of the lock. IMO this is a Scottish Rite Eagle even though it doesn’t fit what we would consider as accurate at this time. Symbols will change slightly in some ways with passing time and distances. That’s to be expected. Two things stand out on this Eagle: There are seven fearhers engraved on the left wing (wish I could see the right wing!) Seven is a sacred number in Masonry. Look at the legs of the Eagle: notice that the lower leg comes off the upper leg at a 90 degree angle. This, also, would be noticed by any Freemason. Now, question is…was Verner a Mason? Or did he include this Symbol at the request of whoever he happened to have made this rifle for?
The rifle attributed to John Shuler on page 275. IMO this is a Federal type eagle, and I see nothing Masonic about it. BUT….look on the next page at the rifle, #65, by an unknown maker. The Double Headed Eagle, wire inlay, almost jumps out as being a Scottish Rite Symble! I’d put my money on it being Masonic!
