This is a wonderful find, it is the HO Scale 1960's Rambler Station Wagon from Tootsietoy. Released over 50 years ago, it is one of only 4 cars that Tootsietoy built in HO Scale. They are all nicely detailed for this scale, and this one is in nice condition with minimal edgewear, and the trailer hitch in tact. 

If you collect Rambler, Station Wagon, Tootsietoy, or have an HO Scale train layout, this is a great find for your collection/layout (1:87 Scale)
