While trying to make some sense of the chaos that is my garage since I sold my other vintage wagon I came across this package of little cars that include two each of a Cadillac Eldorado;Corvette;Mustang(?)and wagons of indeterminate lineage. The part # is 52-7010 Auto Set #1 and what looks like an Athearn logo but no idenification.(EDIT: under one car is a Bachmann logo) I thought they might be N scale(1:144th) but comparing them to another N scale set they appear to be smaller. Any ideas?
