Welcome to the Forum, presumably you are in the U.K. I would enquire of the bigger auction houses when they are going to have an aviation related sale and put it with them.
MK was officailly put up for sale yesterday, seven 747’s and three DC-8’s. There are re-financing talks ongoing, but in the meantime, in the event that the talks are not successfull, the administrator has advertised the company for sale.
