Me and Jack were bored yeterday evening, so we got out my big box of broken track connector clips, and spent the evening making some good ones out of them.
It's amazing how the quality of soldering differs between them, and also the variety of different parts used for the same purpose.
But from what I can work out is that those sets sold in the UK, must have had the parts shipped in, and then assembled in this country, although these shipped in parts do differ from those in Germany.
