This asphalt paver has a few positionable parts: The front loading chutes can be raisd and lowered, and the rear slides can move in and out. The handrails that should be painted black are separate from the main body which should be painted either yellow, or green or any other color depending on what manufacturer you care to represent. This piece is not a particular make/model, but is a midsized piece common on road construction sites. There are four holes in the main body to accomodate a roof, which is offered separately. If you should decide to not order the roof, fill the holes. There is also a set of wheels available should you prefer that 'look' over the tracked version. Should there be an issue, contact me via the designer link or directly via email to email@example.com and follow me as a designer to get the latest updates.
