Thanks! I'm happy to share it...I put a copy of the .skp in my public Dropbox folder. You can download it here:
Hello,
I just discovered this thread, very good work! 
I want to scratchbuild a 1:48 scale Snow-Trac model but can't find any good plan or blueprint, only bad drawings in original manuals 
Do you still have your original sources used for building this sketchup model?
Or please could you share it again (your file is no longer available after 8 years...), it would be better for seeing all the details you put in it?
Many thanks in advance, keep up the good work!
Phil
