Hi Paul,
I took the c/n info for S2-AHL from AvDb which gives it as 32630/368 added to the databse 20/3/2014
In addition CH Aviation from 31st march details the following which backs this up
Biman Bangladesh Airlines (BG, Dhaka) has taken delivery of its first of two B777-200(ER)s on lease from EgyptAir (MS, Cairo Int'l). As previously reported, the twinjets are SU-GBY (msn 32630) and SU-BGX (msn 32629) of which the former, now registered as S2-AHL, has now arrived in Dhaka while the latter is still in Cairo Int'l awaiting its ferry flight.
