Now you’ve gone and done it, Jim!!! Based on your observation, I just went down and opened them all up again. Set #1 indicates on the three individual boxes and on the bottoms of each car that they are 1/43. Neither Set #2 nor Set #3 have any scale info on the boxes or cars. I guess I’ll have to be careful about their eventual placement on the layout so that they don’t look too out of place!!! Based on Set #1, I just assumed that all were 1/43 - maybe a wrong assumption.
The mixer is nice, Lee. It is also the biggest of all three sets. I’ll have to consider adding a construction site to the layout eventually.
I have set #3, and when placed next to 1/43 vehicles, they do look odd. I'd still like to collect sets 1 & 2 though.
