Empirevr Holts just auctioned a paradox, I think it went for about 15,000.00 US. You had mentioned an 8 bore paradox for around 12,000.00, I think that gun(can't be two for that asking price) has had the rifling removed from the chocks but might be a good candidate for a smooth bore ball gun. I believe the gentlemen who has the 8 had a 12 paradox that was bargin priced but the barrels and action had different serial #s but if it is a shooter was fairly priced.
