Yes, Drew, I see them mixed also. So the tubes may pre-date the 1877 change over after the Liège mechanics wore out their Crowned inspectors dies and commenced using their new spangled letter dies. But the tubes were utilized after the change-over, so maybe the tubes or longarm in the white experienced proof and the spangled letters were applied. Too, I've seen that odd >>7 1/2<< stamp near the forend hanger and I believe it was on pattern welded Remington doubles?
