not sold to Iran air but Bek air IIRC (2 of - the other 2 got scrapped in 2013)
also the 4 aircraft were sat at ATH since 2009 but the issue of no-sale was i heard, due to disgruntled OA employees destroyed all the aircraft paperwork & tech logs making them in theory difficult or impossible to sell - that may or may not be true but the Greek Govt which eventually were the custodians certainly could not sell them until now -
it was mooted Virgin would have picked them up for a song but with no paperwork the deal did not go through
