This is the beautiful “Shuttle Truck” from TootsieToy. This was produced by TootsieToys from 1970-1977.  These are tough to pin down as a scale. They are roughly HO Scale, but are sometimes a bit larger than that.  This does have playwear and is therefore priced accordingly, as you can see from the photos, but it also has all for wheels and rolls nicely. It is a great cross-collectible, so if you collect TootsieToys, Vintage Diecast, or Construction Equipment this will be a wonderful addition to your collection.
