I would suggest that it may be D7808 which was HAS (Home Aircraft Depot) 1.27 then 207 Sqn 1927. PD Ascot, AD Aboukir; 4 FTS Abu Sueir 3.28-1-29

207 Sqn were on DH9a at Eastchurch at the time

I can’t tell you the aircraft but I can date the accident

Two photos of the incident appear on Page 4 of the Worthing Herald – Saturday 25 June 1927 though they are very dark
One picture is exactly the same as the one posted

It gives some more info with captions

R.A.F. PLANE DOWN AT SHOREHAM

The scene of the RAF crash at Shoreham, showing the partly demolished hoarding and the telegraph pole which broke of the wings of the machine. Members of the RAF from Tangmere can be seen dismantling the plane

Another view of the crash showing the propeller (left). and mechanics disentangling the broken wing from the telegraph pole. The pilot, who was in the ‘plane alone, was uninjured

What is the source of the ordinal photo ? Even I’m the late 1920’s people mobility was low so if cams from local source to Airspeed crash maybe other aircraft crashed in same local

Does anyone know if EC-CCB was a valid spainish registration and if so what it was ?

Quicker

Hurricanes easier to build – using technology and materials from a large Manufacturer that had not changed in around 10 years

Spitfires. new type of manufacturing requires, a small a niche supplier (I know owned by Vickers, but still built at Eastleigh) needing new tooling and skilled workforce

A service number of 531128 is one is issued from October 1925 onwards to Civilians

Using analysis of similar service numbers based on CWGC web site shows men which ages 24/25who died in 1940 which implies DOB of 1915/1916 so that matches

TRUMAY, LAWRENCE HERBERT Aircraftman 2nd Class 531133 20/02/1940 24
MOULD, EDWARD MELVILLE Sergeant 531169 03/06/1940 25
STEPHENS, CYRIL Sergeant 531100 08/08/1940 24

So it looks like that could match, best next bet is to apply for his full service file (as Next On Kin) or record of service (as anyone else for £30)
