A circa 1905 view of Whalley New Road, looking towards Bastwell, with St Michael's & All Angels Church and adjoining school on the left hand side and the wall to Notre Dame convent on the right.
At the bottom, a section of the OS map for Paul (Please see comments below). Apologies for the blurred image, but hopefully it is clear enough to see what you need. I have marked the property that was the vicarage with a red dot Paul. Just to the left of it, in the grounds, you can see the abbreviation 'Vic'. Cutting up through the centre of the map is Whalley New Rd.
I also found these four images below on Cottontown Paul. They're obviously later than my postcard image, as there are cars in them. The bottom two are of the property that I thought was the Vicarage (No 41 W.N.Rd), but was were the verger was living in my old directories. Cottontown has both labelled as 'The Vicarage', so maybe it was in later times.
