I've only just come across this extremely sad news. Peter was a real character and gentleman - and a truly outstanding modeller. The quality of his layouts, and the skills and knowledge he freely demonstrated and shared, are a true testament to his abilities, creativity and ingenuity.
It has been as number of years since I last saw Peter at the old unit or at the local show in Llanberis, but I have never forgotten his friendly and welcoming nature and how jaw droppingly impressive his models always were.
Rest in peace Peter. The world of model making is a poorer place
