Both of the sold 4s were Roddas. One, in excellent condition, cased in oak and elephant hide with accessories went for well over 100K. The other was rusted, missing the forend, and in general poor shape went for 70K. My rifle will be priced mid way and is not for the dealer to buy and mark up 20-30K but for the high end collector who wants the largest and among the rarest of the vintage English doubles for his (or her) collection.
Email for details and exact price and I will call you. I will be on the road for two months and don't carry a cell phone. Remember, about 50 vintage 4s were made--that makes them more rare than .600s!
