I got one at Beltring but haven't built it yet. It looks very good, no flash. The parts that I tried to fit, did so without a problem. I would call it a must-have.
I'm already working on some decals for the Medium C, comprising 2 versions. One service time version with only a 4 digit registration number and one version of the prototype with the Foster, Lincoln text on the superstructure. The decal set should be completed in a month and will be posted on this forum.
