Some discussion on this old thread here LINK with some good sources to check up on .

More recently Julius DeWaal has done external drawings and Sarik Hobbies also.

Kennions do Rainhill in 3 1/2” which is a LBSC design. It kind of depends on which version of Rocket you are looking for. The loco was very much a development prototype and had many modifications throughout its lifetime some quite major. Rainhill is more typical of later versions. Do buy the book the engineering and history of Rocket. I have a copy and it is fascinating. I don’t remember the exact details of how the book came about but it was the result of an extensive mechanical archeological investigation by either the Science Museum or York Railway Museum when the engine was moved from one place to the other. Extensive dismantling was done and measurements and photographs taken and drawings made. It’s probably the best data set on Rocket you are likely to find.

So a combination of Kennions drawings and the book would get you some way down the road.

Model makers OS did a model of rocket, live steam, I think in 3.5". Martin K and Peter are right about the book, I also have a copy. Noel.

And I see there is a Haynes Manual for Rocket.

This one has never been run since I have owned it or when my late father had it as he got it directly from Hornby when he worked for the company.

I do have all of the bits to fire it as well as the instructions but no track. I may be tempted to fire it up one day. You can see the gas control at the rear of the boiler.
