Sorry if my comment sounds rude, but is really surprising with the amount of CMP Cab 13 survivors around and the many references available (complete walkarounds online, books published on the matter, forums devoted to the type and even original handbooks still available), that the general proportions, shape and detail seems are so poor. Just compare the lights, wheels, cab or body with any of the real ones on the net. More surprising when IBG has made some nice kits before.
