Sordid history of that bird.
It has been through several operators starting with BA. It is an early GE powered -200 (non ER) and as such there is not much of a market for it. It was going to the Government of Gabon as a VIP airplane until the President died and that project was scrapped. The poor thing has been stored off and on several times. Perhaps somebody picked it up and is finishing the VIP conversion.
