The R-1535 Twin Wasp Junior is a relatively rare engine, which may make it valuable to someone who is restoring an old warbird or building a replica. On the other hand, it wasn't used on very many aircraft so the market is going to be limited. I would imagine that most of the major parts are interchangeable with the ubiquitous 450 HP P&W R-985, for which parts are readily available.
The R-1535 powered my favorite airplane of all time, Howard Hughes' H-1 racer. The original H-1 sits in the Smithsonian. Several years ago a fellow built an exact replica of the H-1 and went on to set several new speed records. The replica was destroyed and its builder killed in a crash at Yellowstone. (I believe the crash resulted from engine failure, BTW.)
The web page below describes both the original and replica H-1s. From the article: "There were less than 3000 of the R-1535 engines made, and today they are exceedingly rare. Most are believed to have been destroyed. We believe that the engine installed on the Racer replica is the only known flying example of a P&W R-1535 in the world."

"Run in the house and get me a...."as I open th
