Pauls S1 ironstone hoppers were made from my masters originally intended to be made out of white metal for the Runswick Bay layout of Keighley 7mm group
They were very difficult to produce as the entire hopper was a one piece casting as was the underframe with additional small parts. A few were made for Runswick,
about 20 or so in total but were too difficult to manufacture to market with my other Roundfield Engineering wagon kits. Many years later Paul approached me to try to manufacture some out of resin, I lent him my masters for the two main parts and supplied him with the necessary small white metal parts. Paul managed to get the main parts made in resin and has built half a dozen so far as seen in the photos. The drawing for the wagon was made by using as many S1 photos as I could get in combination with the NER wagon diagram by Peter Scarborough and myself, during development of the drawing it became apparent that the wheelbase shown on the diagram was incorrect at 6' 3" and by trial and error we discovered the correct wheelbase was 6' 0" at which dimension everything fit in place nicely.
Its great to see Pauls wagons and layout and I will watch these pages with interest from New Zealand.
