I know its a bit of a late attempt but like Paul_l I'm going to give it my best shot. Back in the day, not all time expired locos were totally cut up for scrap. Some had their boilers re -purposed as steam supply for industry and heating. What I'm attempting to build is a steam powered saw mill using as much as I can find knocking about in my shed. It won't be a super detailed diorama, more a hint at such a workshop. Anyway I have made a start on the loco boiler using a cut down loo roll and card for the fire box. Still loads to do so I hope you all will be patient . A bit crude but it will, hopefully look better once painted and weathered. Cheer's, Pete.
