This is a Z Scale Barnhardt log loader. Reference the photo for a comparison with 'big brother' in N Scale. This model is reduced from the N Scale version and is therefore a little more delicate to build. Z Scale trucks are required to complete. Please Note: There are two horizontal sprues at the front of the cabin for support during printing. They should be removed for assembly. The loader itself could be carried on any other flat car with light rails mounted to the deck.
