I think MAN Dispatcher you are really going to struggle to get yourself on a 1-11 these days. I was lucky enough to fly on several BAW and BCAL examples between MAN and LHR/LGW back in the day but now your opportunities will be small. I canot see the Trast Aero examples being viable, pretty sure they dont fly scheduled if they now fly at all!! The one in RAK looks rather dusty!
I dont even think getting yourself down to Nigeria would help now either assuming any of those are still airworthy?? Good luck and let us all know if you have any success.
