When it was originally released in 1978 in white with black and yellow tampos, this Larry Wood-designed casting was called Highway Patrol. In 1979, Fire Chaser was a variation of the same casting in red with yellow, black and white tampos. This one came from the Dealer.
This black version with white and yellow tampos is the Sheriff Patrol from 1982 and comes from the collection of Big A.
Another variation of the Sheriff Patrol from 1985 wears metallic blue paint. This one I picked up on eBay.
Yet another variation – also from the Dealer – is this tan color-changing model from 1988 that is both a police car and a taxi cab.
