When Narraganasett Arms offered the Ferguson Rifle, I believe the "issue price" was $ 3,000. This included a wood display stand about 3 to 4 feet long to hold the rifle horizontal, along with the 2-1/2' length saber bayonet.
I think less than 300 were made in this limited issue, but can't remember the quantity for sure.
I tried to sell one of these N-Arms Ferguson rifles seven years ago for an attorney here in town, and after a year, asking $2,750, we gave up, and I returned the rifle to him. He past away four months ago at 60, and I believe the family still has it.
I may try to contact the family again to see about selling it.
