I believe it to be the same engine Ratickle - the background matches the workshop of Daniel and the agent selling it has hinted at it being the same one he sold to Daniel. It is my understanding Daniel may have purchased a re-heated Adour
Apologies to bump an old thread but I believe Daniel's engine as previously shown was an Avon not an Olympus and is currently on e-bay for sale item no: 140899263170
