Cowell, Drewitt and Wheatly were working on the plan for Lidden Estate in 1922.
This estate was Mr Reginald Wheatly's project, but the houses were mostly to designs by Frederick Drewitt.
Note the route of the seafront path, well behind the line of the old seawall that had been lost.
One of the sketch plans included the original layout of the Bolitho Gardens.

I will try and scan the 1875 OS, but it is rather delicate. I will also upload the 1936 OS.
I have a 1786 map as well - I will have a go at uploading some of that.
