WOW
that's light for a 34 foot barrel, John. Were they made from Unobtainium?
You could shorten them some to reduce the weight.
just kidding - I know it was a typo, but 28" to 30" for a double would be handier. I do not
know what barrel length is proper for a flinter, but cap-locks came in shorter and longer
lengths.
F of the A West notes one such SxS at St. Louis that had 48" tubes. The Englishman in the
contest had a SxS with 28", I believe, in 14 bore. Both cap guns.
