Hi Chargerucd,
an English blend can denote a good many things, but at the heart it is a natural tobacco (as the British had a purity law that would prevent additives to tobaccos), which contains Latakia and Virginia, and often more tobacco leaf varieties.
Deluxe Navy Rolls contain Virginia and Perique tobacco, and would thus be a "VaPer" blend. Some blenders like Peterson and Orlik) sometimes call such 'natural' tobaccos English, because they believe the way the blend is cured stoved and pressed adheres to the traditional British ways to produce tobaccos. However, most smokers will only consider a blend that contains Latakia ('campfire'-smell) a true English blend.
