Mike Rayner of "Smallbrook Studios" is developing a 1/12th kit of the following loco to fit on a Hornby 'Smokey Joe' chassis to represent 7 1/4" gauge.

"Talos" is based on "Tinkerbell" and in 1/12th scale will be about 5 1/2" long. A suitable coach will also be made. The kit should be ready in May this year.
He is also continuing to develop the "Heywood" range of Gn15 kits with a saddle tank version of Columbine - "Harlequin" due for release soon following hot on the heels of Katie. I have a Katie on order and as soon as she's built, I'll put some pictures in the Modelling Matters section.
Bert Thompson - a scale Heywood driver for Katie and Columbine is "going into rubber" (Mike's words!) today ready for casting. He is also working on a Couilett/Decauville 2.5t 0-4-0 pannier tank for this range as well.
So a very interesting few months ahead.
Kind regards and best wishes,
Mark
