I do still have the locos, the two Beyer-Peacock 0-4-0's are Springside whitemetal Kits on Ibertren Cuckoo chassis, built as per the instructions, using two-part epoxy. I do have another unmade one sitting on my shelf awaiting construction, which is I think a saddle tank one. The Hudson-Hunslet is a whitemetal kit on a Tenshodo block, again built as per the instructions, but built is such a way that it came apart for painting. The Yorkshire 0-4-0DE is a OO gauge DJH whitemetal kit that I built several years ago for use on a small layout. When I changed scales from 4mm to 7mm I kept it and modified it into the form you see in the photos for use as a narrow gauge loco.
We (my brother and I) built it to show that you don't need a big space to use a large scale, a sort of forerunner to what Gn15 promotes with the pizza layouts really.
If at first you don't succeed, use a bigger hammer.
The only thing that keeps me sane, is the friendship I share with my collection of singing potatoes....
Never knowingly sensible!
