Hi Ray,
that link doesn't work for me ??
the map i'm using is from
www.old-maps.co.uk/maps html
it wont let me clip and paste

type in the post code wd7 9bg and choose ridgehill stables.
then choose the map from the choices on the right. the one i'm refering to was the 1960 post - ww II
if you click the enhanced zoom ( zoom in 3 clicks) and look at the very centre of the map that is the area i'm talking about.
there are two buildings?? and a pond ?? about 20mm above the letters LP. those are what i am enquiring about as they no longer exist.
sorry for the longwindedness of this but i'm not particularly PC literate !!
again i appreciate all help
thanks
Jerry
