The only Lyn kit I am aware of is one produced by L&B models in 014. This is the kit that after a long period of non availability became the Slaters kit. Wheels gears & motor are pretty much the extent of the changes made by Slaters. It’s 1:43.5 not 1:48. Alan Gibson did the wheels for the L&B version.
It was, and remains, a challenge to build. Having been designed for 14mm doing to 16.5mm was a real challenge.
L&B models were the work of David Nicholson. He went on to create ZTC DCC. I’m currently regauging three Lionheart 2-6-2’s for him.
The Link/Gibson Link/Gibson models only covered the 2-6-2’s. Each version was quite different. I now own the Gibson designs but have examples of each iteration.
