Gents,
At some point I will be examining the files in the National Archives Citizens & Business collection (1158 rolls) for the Quimby & Robinson firm.
If their invoices are like those of Noble Brothers of Rome, GA. they will not only state how many guns and what type were cast and sold, but for what battery too!
I would suspect that this firm cast a number of guns for Arkansas units since it was so close to the state.
