This is a 3D printed body for the LMS Fury locomotive for a Hornby Royal Scot chassis, the print is of a high quality, but will require additional parts such as hand rails, buffers and couplers to complete the model.
To fix the body to the chassis, no modification is needed to the chassis. The body is a tight fit and when fitting be careful of the valve gear that may come into contact with the body detailing around the footplate.
Pilot holes are on the model to insert the hand rail knobs and M2 friction nuts to fasten the loco body to the chassis.
If you are using a super detail chassis and Stanier tender, you will need to use the draw bar that has been provided and to hard wire the loco to the tender . For a Fowler tender the drawbar compatibility varies depending on the model, but a simple Hornby drawbar should be suitable.
If you have any questions, please do not hesitate to ask and I will be happy to help.
