Nitromodels is seemingly not burdened with the niceties of numbers: some Cessnas are described as "182" followed by an engine size range, this one seems to me to be just a typical confusion on a particular 182. Some of their photos/ilustrations are less than "picky" about what they are actually depicting. One Cub model shows a picture of a full scale Cub (?).

I would be surprised to learn they knowingly labeled a Cessna 140 that was actually a 140.
