I have been looking at a design for a coal fired boiler for a K27 for 3.5" gauge, and frankly I do not think it is as good as it could be. My problem is that I do not have any proper drawings for the full sized boiler, so am unable to see the actual size of the boiler and its internal layout. Modellers' drawings are not sufficiently detailed to get this information.
Does anyone know if a boiler drawing for the K27's exists, and if so where? If possible I would like to purchase a paper copy or download a scan of such a thing.
Many thanks if any-one can help.
Fred
