1. Make your own (there are videos on working with brass on You Tube )
2. cannibalize another brass caboose
3. cast one via lost plastic

You might also consider copying the parts from an Ambroid or QC kit - metal castings that you could make an RTV mold of and then cast as many sets of parts as needed. Think that the Train Craft kits might also serve similarly.
At one time Bob Lavezzi had some brass cupolas, but I suspect he may have sold those off.
