I have had a Nucast K2, purchased about 1992 by my Dad from one of his visits to Dave Cleal, stashed away for a rainy day (which hasn't come yet!). I've just had a look through the kit out of curiosity. I knew it had the etched chassis. The castings appear to be fairly crisp, eg the edges to the running plates and rivets on covers for access to superheater header. I've also got the latest Markits wheels, Maygib sprung GN buffers and a turned brass chimney as extra bits I've accumulated for it along the way. I note from comments you have made previously with the original version of the kit that the cylinders didn't fit, the piston rods were too short and motion bracket too high. I look forward to hearing your comments on the 'updated kit'. Judging by what I see the cylinders must now fit ok?
Regards
