Following up on my entry earlier today, the omniscient Keith's Mum has once again set me on the correct path.
The comment just arrived:
Keith's Mum thinks that the Bird's Eye view on Bing Maps would give you a better view of Warren Hill Cottage and Stelvio Cottages.
Now, I have found that it's best not to ignore Keith's mum. The suggestion above reminded me of information sent by the ever-reliable Barry McAleenan regarding the 1899 map he scanned for us:
• Plot 81 became Stanton Prior
• Plot 80 became Stelvio Court
• Warren Hill site, plot 77, now  includes Stelvio Cottages.
You can see the locations he mentions on the detail of the 1899 map of Eastbourne, above, left.
Having never warmed up to Bing Maps, I decided to give the suggestion a try and am certainly glad I did. Below, you can see the image Keith's mum recommended, and it's far more useful than those available at Google Maps [click any image to enlarge it in a new window].
And here you can see the view of the same location, around those Stelvio Cottages, pivoted around and from the north:
It looks to me as if the building with the lighter-coloured roof is more alike to images and maps we've seen than anything else [below]. One has to consider the fact that it may be the elusive "last vestige of Warren Hill School." There is a comparison of the southern Bird's Eye View image with a crop from the 1930 black-and-white image of Warren Hill, circa 1930, showing Warren Hill's latest addition [below].
The overall appearance seems correct. The chimney seems correct. The roof seems correct. The white-cornered wall seems correct. The location seems correct.
Keith, please give the old girl my best, will you? She never fails!
And if you are wondering why I wasn't enamored with Bing Maps, here's the first thing I naturally looked up when it came out: My house. I've made all of the settings identical to the ones used to render the beautiful colour images above. You can see it as I see it, at right [clicking on it will not improve it whatsoever].
The orange push-pin indicates the exact location of my own dwelling. Lovely, eh?
Yuck. (Is that also a British expression of disgust?)
Thanks for getting me out of my own dull and poorly pixilated neighbourhood and into the real world…
