There are three questions to ask regarding this topic
What was the committee of safety?
The committee of safety was a group of Americans that took over government from the royal governors and crown law makers. they raised militias (mostly for their own protection), collected revenues, imposed temporary laws. You’d use view it as a type of marshal law system that quickly seized control.
And what was a committee of safety musket?
A committee of safety musket is a musket that was surcharged by the committee that took possession of it when they seized political control. These muskets were often militia grade muskets, older and used, many restocked in North American maple and cherry. These muskets came from a variety of sources, some were British, many were Dutch, some were British surcharged French and Spanish muskets (in the south). These would have been stamped U.S. and by the armor that maintained and storekeeper that recorded them.
What are american muskets ?
American muskets and committee of safety muskets are really interchangeable terms.
Many of these muskets had Americanized features, such as long land Bess’s that were cut down, restocked and had royal markings filed off.
An American musket can really be what ever you want it to be. Moller and Neumann book show many specimens that are simply a hodge of parts lobbed together on a stock, some of these muskets do not have parts that go well together, some do.
There is a pretty famous American Musket with a french 1717 lock, home made barrel bands, a cherry stock and a brown bess barrel or Dutch barrel. I believe it is on display in Princeton NJ.
We often use the term committee of safety to represent a militia musket or american musket, its simply become a catch phrase for Americanized Musket or pre-revolutionary colonial restock.
Does a commitite of safety musket have to be a pedersoli or miroku defarbed, absolutely not. Kit Ravensheer and many other builders did defarbs of these over the years, to simply remove the modern day features of the muskets to make them appear more authentic.
My own personal example, i have a pedersoli bess in parts (hardware, lock, and barrel) that I’m restocking in cherry, and having the barrel lined down to .62 caliber, brining the pedersoli musket into a broader category of light infantry fusils. The Lock I am removing the markings (with an MIG / TIG Welder) and just stamping U.S. on the Tail. The stock is a copy of a pedersoli stock with more wood in the butt for some alternative shaping.
