Agreed, but once you've added wheels, motor, gearbox, and buffers you're looking at around £100 on the workbench. And brass is cheaper than nickel silver. There's a lot of rivets to be pressed out, some of which are very close together, and some careful curving required on the engine casing. Seems a very odd prototype for Mike Edge to do but perhaps there will be sufficient sales amongst LMS modellers of the pioneering diesels, thus making the NCC version a simple add-on to offer.
Mine's already started with the frames set out for my first foray into continuous springy beam (csb) suspension as an experiment using High Level Kits csb stuff - if I get in too much of a pickle then it'll be easy to convert to flexichas having already done the hornblocks.
I did also see the part-built WT from Worsley Works at Scaleforum - seems nice although the rivets look very heavy to me. But once finished and painted they will get knocked-back. However, fear not the riveting as there is a skeleton bodyshell to which the overlays with etched rivets are attached by tack soldering from voids on the inside. Be interesting once the chassis is offered.
