Wooden offset-cupola caboose from included photo. It's not very prototypical, but least the ATSF had cabeese with a similar body outline... 
This is a reskin of Josh Harvey's cp_caboose. The mesh and associated files where created by Josh Harvey. Many thanks to him, and to Sandy Gervais(sandman2) for posting it to the DLS after Josh disappeared! 
I just reskinned the BMP and TGA files and fiddled the config a (very) little. There are four interior views in this cab: two standing on the platforms, and two in the cupola
