Vickers Valentia K3599
K3599 is the first production Vickers Valentia Mk I.
The Vickers Valentia Troop Transport (not to be confused with the Barrow-boat Vickers Valentia Flying Boat) has its origins in The Vickers Victoria 
It was developed through a series of variants of the Vickers Victoria, with the initial production models (Mk III and Mk V) being powered by various models of the Napier Lion engine. The final variant of the Vickers Victoria (Mk VI) was powered by two Bristol Pegasus engines and cleared to a maximum take-off weight of 17,600 lb.
Vickers (Aviation Department) recognised that with this powerplant, there was enough scope for development to higher-weights, following only relatively modest structural improvements.
They instigated some main external changes such as the strengthening of the undercarriage (by the introduction of a diagonal bracing strut in place of the previous wire bracing) and the fitting of a tailwheel, rather than a skid. The presence of a tailwheel, together with the diagonal bracing strut in the undercarriage are the main external distinguishing features between the Vickers Valentia and the Vickers Victoria VI and they both used the Pegasus engine. With these changes however, the operating weight was increased to a maximum of 19,500 lb.
Bearing in mind the similarity to the Vickers Victoria, the Air Ministry decided that a new type name was need, not least to differentiate the types and to reduce the risk of the earlier aircraft being loaded to the new weight limits. This resulted in the placing an initial production order for what became the Vickers Type 264 Valentia I, with the first example being given a military registration (K3599).

K2797 was converted from a Victoria V to a Valentia I by Vickers at Brooklands.
The fist of the type flew in 1934 and in total, 28 new build aircraft were ordered in four batches, these being were delivered between May 1934 and May 1936. Because of the relatively modest changes from the later marks of Vickers Victoria, a total of 54 additional aircraft were produced by conversion, many of these being completed by the RAF in the Middle East.
Experimental developments included installation of a sky-shouting public address system on one aircraft (K4632) and the development of defensive gun positions on another (K4633). Several 'in-service' aircraft were subsequently converted in this way.
One aircraft (K3168) was converted as an air-to-air refuelling tanker and used for trials to deliver inflight fuel to an Airspeed Courier, this in support of a proposed non-stop flight to India to be carried out by Sir Alan Cobham.

Despite their apparent obsolescence, the RAF had 60 Vickers Valentia aircraft on strength in September 1939. Eleven Valentia aircraft were later transferred to the South African Air Force in 1940.
The type remained in service on communication duties in North Africa and the Middle East. The last operational examples (K1311 and K3600) were still in use with the Iraq and Persia Communications Flight in May 1944.
