This is owned by Stobart Air, part of Stobarts transport group it was at Southend Airport, until a month ago, when it was transferred to Carlisle Airport, both operated by Stobart Air.
There is a 1:76 model of this via World of Stobart Atlas Editions, made by IXO. Hard to locate sadly even on Ebay. Goes with a Scania Angloco 6x6 in the same series also from Southend Airport. Look like very nice models.
