Thank you for viewing. This is a C-beam transformer loading set, 3D printed, compatible with Micro Ace A8576 Shiki 801 B1, for large freight car B2C, drop-in type. It is designed using 3DCAD and output with a 3D printer. This is a set of two C-type load-bearing beams and a transformer (roof and body). I bought the Shiki but couldn't get the transformer, so I made one. I wanted a different variation from the product, so I made the C-beam. The product's load-bearing pins can be used for assembly. It shouldn't be particularly difficult, but please contact us if you have any questions. This is designed to fit the model, so there are many differences from the actual vehicle. The transformer is not modeled after a specific product, so please enjoy it for its atmosphere. You can enjoy it with the material color, but it can also be painted like plastic products. Shipping is free. We will use Japan Post's Yu-Packet Post. (Tracking, delivered to your home mailbox) No claims and no returns, but please feel free to send us any requests for improvement. Thank you for your consideration. Vehicle type: Freight car Manufacturer: Micro Ace
