Just missing out on my last post is this model
An LMS diagram 1945 Long tube. It uses a Parkside BR tube kit which has been shortened to 30ft 6in over the body (122mm) and 17ft 6in wheelbase (70mm). The corrugated metal ends have been replaced with planked ones from plasticard.
A bit of a family tree starting at the top with an old Ian Kirk kit for the diagram 1675 wagon. The wheelbase for the top 2 are the same.
Just a couple of pics for the hell of it!
