I collect English blackpowder double rifles and in the late 60's and 70's there were plenty available coming in from India. I was young at the time and could only afford one cheap double at the time. I remember seeing a table at the Ohio Gun Collectors show in the early 70's that had at least 10 blackpowder double rifles on the table that were $500.00 EACH. A gunsmith from England had brought them over after going over each one. They have been a good investment for me over the years, but I do wonder when the well off guys who bought the high class stuff start liquidating their collections, who will be there to buy? Not very many young people have any interest with collecting anything! I still think there will be a climbing market for the high dollar double rifles, as they have world wide appeal. I hope I am right as I am betting on that instead of the stock market!
