German Armored Rail Draisine
1/35
The DML armored rail draisine. Basically a railbound tank. As with many of my models there is a lot of metal in this.

These were used in Leopold Regiments as their very own Department of Homeland Security patrol cars.
All the little tie-down rings along the side are metal replacements. 

Tool clips are metal replacements. 

Pretty, ain't it?
These bumpers are metal. I tried to make them look like they'd been slammed around a bit.
The T-shaped handles on the loader's and gunner's hatches are soldered metal.
Here you can see the main tactical flaw in a rail-based blitzkreig. They didn't have enough railroad track....
