The four-axle M-23 was the largest airport crash tender in Oshkosh’s range at the time and entered service in 1977. This giant fire fighter is comparable to the vehicles from Faun and Rosenbauer.

If you dare to build this P-15 or M-23 as a 1/25 or 1/24 scale model, you could use the wheels and rims from Revell’s Simba kit. I once had a drawing of the M-23 printed in 1/25 scale and laid the Simba wheels on it. They fit 100%, as if made for it.
