I assume HP is short for Highland Park - I haven't got any experience with the brand, but I will keep it in mind for a later occasion, as I see there are several bottlings available over here.
It's not on the short list for this particular search, though, as I have my mind set on acquiring something that's aged quite a bit longer than the HPs I have to choose from at the moment. I am quite curious about what such a long time, perhaps some 40-ish years, does to a fine single malt.
