Hi Steve,
I believe it was Vintage Fabrics at Audley End. The colour scheme, markings dimensions and locations came from my files following Declan contacting me.

Great pics, looking at the pics showing the upper surface I notice that the walkways have a yellow surround. Never applied on the original scheme and not on the Air Corps instructions issued by the drawing office. Just wondering is this a new instruction/regulation ?
