I’ve just acquired a 1933 ‘Sidcup and District Free Press’ which has a page of adverts for Blackfen. Here are R. E. West hardware stores, Woodlands Post Office and H. E. Rowbottom grocers in what was then called Woodlands Parade, opposite Sycamore Avenue. Plus in the house alongside, the rather fabulous Blackfen School of Music, Dancing and Elocution. The photo is 1934. And lastly, the same view today (2019).
