Welcome to the board Nick.
The following may help.
For a chassis there is a suitable one listed here -

For an example of a Kays white metal kit built loco there is an example here:-

Really you need to locate a Kays kit and they went out of production some time ago. The question is has somebody else taken over the kit production or does someone have some old stock somewhere.
There is always the old Lima model as a last resort which can be picked up secondhand for about £30 if in good condition.
Happy modelling
Gary
