here are some numbers regarding costs:
We can see from the Fur trade records what the costs were.
from Inventory of merchandise, etc. delivered to the Northwest Company, at Okunaakan, and Point Matthews, November 22d and December 3d, 1813.
a common musket, new : $11.00 used: $10.00
lock, stock for ketland gun new $3.00

Saint Louis March 28th 1832 R. Campbell
Bought of J & A Kerr -
6 doz Butcher knives No 4778 @$1.58
5 Rifle Guns @$13.00

much later, in 1883
BOWN, James & Son ”” (James and William H. Bown), Enterprise
Gun Works 136-138 Wood St., Pittsburgh, Pa., from 1871; 121
Wood St. in 1883; bought out by Brown & Hirth in or before
1886. In 1883 advertised percussion fullstock rifles at $15, half-
stocks at $12 and $20, double rifles at $35, and double rifle-
shotguns at $30.
---------------
So, between 1813 and 1833 a common musket cost $11, a "rifle gun" cost $13.
in 1883, for comparison purposes, half stock percussion guns sold for $12, fullstock for $15 and
double shotguns for $30.
Since a double barrel gun would require 2 barrels, 2 locks, a more complicated trigger, a more complex
tang and breechplugs, and most important, soldering and correctly regulating the barrels together.
Not to mention twice the weight.
Thus we see the cost of a double would be *more* than twice the cost of a good single, and considerabley more than
a "common gun".
Double barrel shotguns were preferred by the Traders for night guard duty on the trail,
but were bought by the Company.
