So you know, this model came from the September "ex-Lesney employee" auction with Vectis.
It is a 42B Studebaker Wagonaire painted in what seems to be a totally unique blue-green. The roof slide seems to be an ordinary light blue but the body casting is uniformly coated in a blue-green that doesn't really totally match anything on my collection shelf. I've attached some photos for review. Let me know what you think best explains this model. Lunch-box special? Fake/modified? The base has a tow guide. The roof slide does NOT have the "B" on the underside.
