The other Dan's idea to post a picture seems a good one. His work looks good unpainted and so that method would be appropriate. Eduardo's point about the Revell kit is true: it is a bit of a waste of a good kit. Not quite what you would say about the poor old Esci version.
Anyway, here is a major rebuild based on the Matchbox Comet. Very little of it showed by the time I sent it off to Milicast to be moulded. It does, however, show the track as adapted.
