i think its a 2012 "ripper", not a pk ripper. the ripper was the cheap (£200 ish) one, its obviously been tarted up with lots of non original parts. if it is a ripper, it has a small top tube, 20" more aimed at earlier teens rather than adults.
it is not a retro series se, they have all had looptails since being introduced in 2008. if you go on the se website, there is an archive of all the ranges by year going back to 2006.
bearing in mind, the current retro rippers are between 400 - 500 quid new, depending where from, surely the best option is to just buy one of these? the 2016 model will be out soon.
wouldn't touch that ebay one with a bargepole myself....anyone who tries to pass off a ripper as a pk ripper is not to be trusted.
