I think that Staunton Depot flags were slightly different materials wise on some respects that the Richmond Depot flags. Additionally, the flags from there only supplied Early's Valley Army in 1864 whereas the preacher who got this flag had a church in Petersburg, which was well within the supply auspices of the Richmond Depot.
I will have to dig into my flag file for the Staunton Depot to recall how they were different. If someone beats me to that it works for me.
