Wearhead Engine shed ref

Hi, here is a section of map I am using as ref from 1950 of wearhead:

Go here and click on the launch GIS, from ther eyou can go back through old maps of the durham area. been a great help plotting the route.


Here is a picture of the engine shed, I have a few others that show slightly different views but none give me a full idea of what it looks like on all sides, I will make my best guess.
cheers
