I have built InterMountain Santa Fe Refrigerator SFRD 32153 with help from from others on this list.  I upgraded it with the usual such as wire grabs and unusual such as the ice hatch hooks to hold the ice  hatches open.   I  cast an underbody in the M&N Shops to replace missing part.  If you are interested in the build of this reefer, photos and writeup of the build process including painting and lettering are now available on my blog I have to share photos and writeup of modeling projects on my Minneapolis & Northland Railroad Company.   If you would like to take a look please do at the following link:
