I've had pretty good luck picking up Rivarossi articulated parts on ebay. There was thousands of them sold and many of them have been cannibalized over the years. Do a search for "Rivarossi locomotive parts". Something will pop up in a few days.

Hello,
As a project of mine I wanted to start doing, I have designed a monster of a locomotive, a custom quintouplex with a single cab in the middle, I have been on the look for cheap mallet rivarossi bodies, due to the fact the rear wheels areticulate a bit to make the whole thing come together. Where might I find bodies and frames of rivarossi steam locomotives to complete this quest? the only other thing i have is to make a large coal and water tender.
Thanks!
