I was asking because I don't think I built the WIKI to reflect that, as I wasn't aware.
To make it more confusing, even my Rooney Urn purcased from ClassicChaving (a Rooney vendor) from the old stock, was marketed on their site as a PL1 (Polo 1, I assume).
I think it's one of those things like Kleenex, Bandaid, Skidoo that people just use the most popular marketed name (or original in may cases) as a generic term for the item.
