A well-made, early stage GWR Prairie to Martin Evans' "Firefly" design.
Work to date is a nicely done set of frames with split axleboxes, a set of boiler plates with substantial plywood formers and a set of unmachined wheel castings. There are four machined cast iron axles boxes for leading and trailing wheels.
There are pictures of a finished specimen in the archive. Castings are still available from GLR Distributors.
