The Gun Slinger was designed by Larry Wood. It is a highly imaginative fantasy car designed to look like a six-shooter revolver.
It was released in 1975 as part of the "Flying Colors" series. Model 7664 with Redline (RL) wheels is from this first year.
This is one of the most unique fantasy castings ever made. The main body is shaped like the cylinder of a revolver, the front end resembles the barrel and sight, and the rear has a spoiler shaped like the hammer. The driver sits in one of the "chambers." The first release was chrome plated.
As a fantasy car based on an object, it is similar in spirit to castings like the "Hot Heater" (a Zippo lighter) or the "Sweet 16" (a party favor).
The initial release was chrome. It was also produced in gold chrome. It was a short-lived casting, making it a collector favorite.
