Research letters for most L.C. Smith shotguns finished from 1918 to 1950 will include the shipping destination. The destination for the military shotguns was "Rochester Ordnance".
I agree with Dr. Drew that the USA-F is a barrel inspector's mark. Most shotguns with the USA-F mark were shipped to private companies and individuals and not to the military.
