This is a really nice 1/34 diecast from First Gear. I reall like these trucks, but I only buy one when I get a really good deal. It would be too easy to start a whole new collection of them.
The Mack B series was a line of heavy trucks produced by Mack Trucks between 1953 and 1966. It is regarded as the best known Mack model and many still survive both restored and not. They were available in a variety of configurations, including as fire trucks and school buses. The B model was replaced by the Mack R series models.
