Several years ago I responded to an ad on Gun Broker (I think) about a Roy Dunlap Model 70 Winchester in caliber .300 H&H Improved. There were no photos included in the ad and the seller had none to send me. I finally decided to take a chance and placed a bid. It turned out to be a winner (I was the only bidder), but to give myself a little cover, I got the seller to agree to meet me to make the delivery face to face.
There is a good bit more to the story, but suffice it to say that I was pleased with my purchase. The Model 70 has a nice custom stock and the barrel was marked not only with Dunlap's name, but also the name of the maker, Bliss Titus.
The stock maker was not identified in any way, but the fact that John Hearn is featured prominently in Dunlap's book on Gunsmithing and the resemblance of the checkering patterns to Hearn's work as shown in Kennedy's book, led me to ascribe it to him. One particularly characteristic feature of Hearn's checkering was on the pistol grip, where the wraparound pattern extended from the very bottom all the way around to the other side, so that only a thin line separated one side from the other.
An additional element in the transaction was my discovery that in the late 1940's the Wimbleton 1000 yard rifle match at Camp Perry was won by a shooter using a .300 H&H Improved caliber rifle with a Bliss Titus barrel.
