David, yes I am T J Mallard of Rossendale!
I'm interested to hear that Slaters are planning to release a kit for Lyn and likely the Manning Wardles - it makes sense as they've released some of the coaching stock. I am also aware of the EDM owned ex Gibson kit and it's extended gestation. Whichever end up being released I am sure they'll make nice models.
Overall it's good to hear that the preservation movement and construction of replica engines is generating interest in this prototype as modelling subjects
