T- many of the old time gunsmiths purchased locks, but made barrels, made stocks. Yes, it was very labor intensive (for a rifle, cutting the rifling, 100 passes up and down the bore for EACh groove, hammer forging a damascus barrel, grinding the flats on a barrel by hand, etc.
In terms of hours worked to pay for a gun, they are MUCH cheaper now than they were back in the day. That was also a time that, unless you were VERY wealthy, you might own one gun in a lifetime.
What we have here is... failure- to communicate.
