There was a very nice 1-11 srs 500 parked up at Maiduguri. If I can master the intracasies of how to put a picture on here I will post a couple of pictures that I took of it in mid 2005. Rumour has it that it is in flyable condition and in mid 2005 there was a possibility of it gaining an exemption to allow it to fly out of Nigeria. I don't know if it did though.
It used to be G-AYOP with BCal.
I used to work with that very same 1-11 at BR Cal. i have not seen it for years but i think it is ready for the graveyard now.
