Thanks scosgt for the reply.
The possible Springfield Armory connection would make it's history even more interesting.
All the photos in the Canfield articles show shotguns stamped with U.S., + the proof P, R.L.B. and the bomb.
The plot thickens.
As you can tell, I really like shotgun just as it is, so more history just sweetens the pot.
Thanks Again,
Stay Well,
