Your wish is my command!
An aerial photograph showing the station, dated 25 August 1952, is available at: http://www.britainfromabove.org.uk/image/eaw046201
If you register a free account on the site, you are able to zoom in far enough to see detail on the signals (the free download only gives a low resolution version, sadly!). I am unable to see any evidence of a distant arm on BS5; BS6/7 is difficult to see due to background trees; BN 16/17 (post-1955 numbering, if it matters) also show no evidence of distant arms.
An eagle eyed person among you may be able to work out if any arms are under BS6/7 on this photo (7 Oct 1959): http://www.nrm.org.uk/ourcollection/pho ... 9_RJS_SV_1
Definitely gone by c1961 (link
