Am I the only one here who finds an add joy in pairing up models of the same car but in different scale? Take this for example:
On top we have a brass HO model from Overland and below is a G Scale version. Both are of Reading RR GP-35 #3640, the only GP-35 to wear the all-green-machine look that the Reading used prior to Conrail.
Or this pyramid:
On top we have Z Scale, then HO Scale, and finally G Scale - all of Procor covered hoppers.
Finally, I present this image:
On top is Z scale and below is G scale, both are black Procor tank cars.
