I started another thread with pictures of a Hawken style rifle built by Taylor Sapergia, which just also happens to be left handed, because that is what I want to shoot. The market for left handed guns is 80% smaller than the market for right handed guns, so if someone plans on shooting it, or is looking for more HC/PC (I know there were left handed rifles back in the day but they were far less common than they are today) you have a MUCH smaller market to appeal to.
In terms of value, to have Taylor make the same gun I posted you would be looking in the ball park of 8-$10,000 today. I bought the rifle I posted used and I can tell you I didn't pay anywhere near that for it. Taylor is one of the top ranked builders of our day and the quality of his work and artistry is well acknowledged but his guns are still just modern replicas. Maybe 1 or 200 years from now they will have appreciated in value a significant amount, but currently they sell at a big discount to their new price, just like most modern builders and modern centrefire arms.
As I posted earlier, this is not where you want to invest your retirement funds.
