I first met Len at an exhibition where he was showing off his latest invention - a 4mm brick building system. He was very interested in our Layout that we had at the show and asked if he could come along and join our little group (east London S$ soc).
On chatting with him he explained that he was a pattern maker and was looking for something to relieve the boredom of making double glazing bits. We suggested he made some better scale track and so K&L came into being (Len changed the name to C&L shortly after. I took the first bit of track Len made to an EM expo and showed it around. It was criticised by a member of the EM Soc. for the rail being to close to the ground. On returning home Len and I went over the track with a fine measuring device. The only thing that wasn't completely scale was the jaws that hold the rail. That was because the rail couldn't be drawn to scale dimensions or it would disintegrate when you tried to use it. We were pretty sure we were right because we had purloined an actual chair from a disused siding in Gidea Park. Both Len and I then decided we could probably make a turnout from the chairs and so the first point was built, one by me, one by Len. We both produced them at the same time much to everyone's amusement.
There were some modifications from the early chairs mainly at Alan Gibson request as he saw more potential in a less specific design which could be used in any gauge and it was he who first took on the retailing of the system. From that time Len made many more different chairs and rail fixings and most people are aware of his track by now if not the origins. He was constantly inovating and even in the last few years had produced pattern drawings for even better track.
He will be sorely missed and his contribution to making our railways more realistic and more prototypical has been immense. I'm sure quite a lot of people who had never built track were encouraged by the availability of lens track system.
I shall miss him too as friend for many years.
