Good comparison shot between 56007 and the donny built one, I don't know if it's the camera angle but the multi receptors on 007 seem a tiny little lower than the British one. Good choice with 126 as it was the last one in large logo iirc.
Just had a look through this thread and it's a fantastic depot, just how I like a layout done slowly with massive attention to detail.
Look forward to watching it progress especially as there's a big 56 presence.
