Alas Zubi, it is not a kit.  If you are familiar with the mylargescale masterclasses, and the kits offered by Bronson/Tate  you will know where I started from.  I took the original cada data and completely redid it into the model I mention, then cut it at a local maker club.  The trucks are 3d printed models of the same design as Dan Markoffs combine.  They are available on my shapeways site, steamfoamer.  The pedistals are cut from aluminium the you would have to make.
If you would like photos send an email to steamfoamer@live.com

Hey B'mann

I just finished up a scratch built Fn3 laser cut model of Dan Markoff's combine Elsa.  I notice that you folks have released your Jackson and Sharp coaches in that color scheme.  I am in the process of developing the cad data for the matching coach.  I think these would make an excellent replacement for the outdated g scale coaches.  They are different enough from the Accucraft coaches to make them instantly recognizable and they are 1875 prototype that match perfectly with your American and Mogul engines.  I would attach photos but, i can't seem to resize down to 128kb.  It is posted in earlyrail yahoo group.
