For those wanting a ZL kit there is a delay as Peco stopped making their NR112B underframe that was used to complete it.
Consequently, I have re-evaluated the kit and have decided to produce the more common 6-wheel version and include a 3D underframe as part of the kit.
Each kit will come with 1 ZL lasercut etch and a 3D printed chassis and 6 wheels.
Currently I’m revising the instructions to cater for the changes. Photo courtesy of Paul B. Photos shows old chassis style
