Hello Daryl,
If you are talking about D6864 shown with the chequered fin in my artwork in our decal sets (taken from the full-size vignette at Omaka) then I'm sorry to say that no, it was Viper engined. It was part of an order for 150 built by Wolseley Motors in Birmingham (themselves manufacturers of the Viper engine, of course) the serial range ran from D6851 to D7000.
D6864 was delivered to the RAF at 1 AAP, Coventry 27/5/1918. It arrived with 74 Sqn on 1st June. Major Caldwell used it to shoot down two Fokker D.VIIs on 15th July and 4th September before the mid air collision the following day brought its career to an end, it was eventually deemed not worth repairing and struck off charge on 17th October. All this information is taken from The SE5 File by the late Ray Sturtivant and Gordon Page, published by Air-Britain in 1996.
Sorry to disappoint. The Roden kit is not Wingnuts quality for sure, but it can produce a decent model. Alternatively you might consider a conversion of the WNW Hispano kit or even hope that someone produces a conversion kit for the Viper variant.........
