Interesting set of reasoning over on Phil's blog with his Radial from a K's kit and parallels with here. It's important not to throw the baby out with the bathwater and assume that newer is better or finer or more suited to your needs. I could go to town and upgrade the Terrier, but why? The duck analogy comes to mind - it looks like a duck... etc. The spec is as follows: 1960s(?) K's body kit, Branchlines chassis (90's) transfers Maybex, Romford wheels on EM axles, Mashima motor, and Goden Arrow plates. There is still the huge screw on the front as a fixing, but hey, Les Darbyshire's example appears to have the same deal on his Maidstone Road in MRJ, so if it's good enough... This small side project may have some legs.
