My good friend Randy of Fidelis Models http://www.fidelismodels.com/mm5/ stopped by the house and gave me a box of crappy, used up old Roco models. Everyone was missing parts, or severely damaged.
The vehicle has been stripped and left to rust away. The gun has been removed and so have the wheels and tires. They can be used on other vehicles.
The model did not come with a gun or mount, but did have wheels. I removed them so that I could use them as spare tires on other 234/ series vehicles.
