I got this song from my Dad. He learned it in Jordan Valley, Oregon in the late 30s. I don't know who he cowboyed for over there but most of the hands knew the song. I also heard an old timer up on the South Fork of the Salmon River sing it when I was working for the Flying W in Big Creek, Idaho back in 1974-5. The words from both of them are pretty close to what you all have - the gear was as follows from the two sources I got it from:

Now Bill you take my saddle,
And George you take my bed,
Jack you take my pistol after I am dead.
