1960's 1:87 HO scale Macclesfield plastic station building, made by Playcraft
There were two versions of this model - "Bletchley" and "Macclesfield". You don't really see too many of these models. I would hazard a guess that a lot of them will have been disposed of, because they are too small for OO gauge modellers to use and as a result, they are a low value item worth just a few £ depending on condition.
This one had been on the layout for many years and I gave it a wash (carefully) in the sink full of warm soapy water.
