Hacker Martin's rifles are quite collectible and there's a fair amount of interest in them. There was a Gun Digest article on him, although I can't remember the year. My dim recollection is that one of his last rifles was made for the actor, Slim Pickens, who is pictured with his rifle in the article. Given the quality of Martin's work and the collector interest, I'd predict that the price will be a lot closer to $5,000 than $1,000.
