Hi all

In my ever increasing beer car collection I have these two, that I found separately, from some time ago. I initially had them dismissed as just another two 4415 beer cars, albeit identical and just different colors. I also know of (and am actively looking for) a third one thats colored red. I have tried looking through Kolls and other searches and can't seem to find any information regarding them. Are they a set of three (possibly more) that came together, or just a bunch of identical but different colored 4415 models.

Any information would be appreciated, since right now I have nothing!
