Theres been quite a lot happened since the last update, but I don't feel like writing up an essay on that right now, and I don't know if I'll get the time tomorrow.
Nevermind, I'll show you a project I've started since the last update. I had started to convert a Hornby railroad A1 to an A3, but I realised I didn't have the confidence to finish it before it was too late. So, I cut the smokebox and the front of the footplate off, and glued a GBL A4 front on.
This was part of the smoke lifting experiments that were carried out on 2751 and some others, I'm not sure what identity this will have when it's done yet.
