Good Morning,
Were any of the builders of these rifles Masons?
There are Masonic symbols having the configuration of the stampings on these rifles. Sounds "far fetched" right. Not really, there were at least two dozen Masons working at Springfield Armory during the period from 1796 through the early 1840's and probably beyond that date as well. Some of these Masons had stamps with Masonic symbols and used them during their duties to mark the musket components they worked on, as required in Armory Regulations. Two of these identified symbols were the Ever Seeing Eye and the Square and Compass. This is all documented in a
Man at Arms article in Vol 35, No. 4, August 2013 by Kent W. Johns and Peter A. Schmidt. Also in Appendix F in the book
Springfield Armory Infantry Muskets 1795-1844 by Kent W. Johns, published in 2015 by Mowbray Publishers.
I've attached a sheet I found, during my research for the book and magazine article, showing some of the many Masonic Symbols. Please notice that two of the circle symbols bear a striking resemblance to two of the symbols of two rifles posted in this thread.
Also attached are two of my personal photos that show Masonic Symbols on the lockplates of two Springfield Armory muskets, one dated 1806 (Ever Seeing Eye) and the other 1823 ( Square and Compass). I've identified eighteen Springfield flintlock lockplates with Masonic Symbols.
Just a thought. Thanks for your attention.
