This is a metal kit, so be sure to clean off all the flash left over from casting. PREFIT all the pieces before gluing. In following the instructions, I found it much easier to rig the C rigging BEFORE A & B I left my pulleys exposed metal. (Easy to scrape the acrylic paint from the metal, making it look like you're a great painter!) The rigging is what makes this kit and you can skip one glue step so the shovel swivels for more realism. Looks great next to the n-scale dump truck by the same company. Now that I'm used to these, there are a couple more I'm going to get.
