A Yahoo/Alta Vista search for lum+abner turned up 73 references, including the National Lum and Abner Society. That might be a good place to start. Since Lum and Abner were Arkansas boys, it is possible that the Ozark Cultural Resource Center archives might have the sheet music that you are asking for. At the moment, though, searching for it would be difficult, as they are still recovering from a recent remodeling, and many items are still packed away.

Note: I sent this once, but for some reason, the new screen ended after Ludy's original post, making it impossible to read my response, or more importantly, to make any new responses. So I went back in time (Isn't it amazing how we can do that on the internet!!??) and posted it again.

Yeah, Dale, but you left out the quote marks at the end of the URL both times. The quotes are optional, but you have to either have them on both sides of the URL in the link, or not at all.
