One of the first kit wagons I built was the Cambrian Turbot. Back then it had super fragile bogies but was, and still is, a decent kit. The current version comes with one piece bogies so they don’t tend to disintegrate as soon as you look at them anymore.
A while ago Justin Newett of Rumney models produced an upgrade kit for the Lima bogie bolster E and since that where the Turbots came from it seemed sensible to use one of these to update my ancient and small fleet of Turbots. (Kind of the reverse of what BR did.)
Above is a comparison of the new underframe and the old. Because of the good design of he kit its dead easy to build although I did have to cut the baseplate in half as my solebars were closer together than the Lima model’s.
The view no one will ever see! These are the newer type of one piece bogie which Cambrian do as a spare.
