I cut and pasted this from a GUNS magazine ad (1956) in the 'Some Rifles Just have It' thread.
Flaigs, Midvale, PA ad for Boehler Steel/Sodia mfg ribbed-oct/rd and also plain rd bbls both fitted and unfitted.
Not 1800's of course,,but 1956 is good starting point as any.
Cheap prices by todays standards but the average guy didn't make much either. It still shows the 1/2oct/ribbed bbl to be more expensive to buy and $5 more than the plain rd bbl to fit to your action.
Only a single snippet, but a common one from the era.
