B Class registrations

Hi,

Is there a database for the various B Class registrations that were applied to British aircraft that were destined for foreign airforces?

I am trying to locate the registrations that were applied to the various Strikemasters that were sold abroad. They were in the G-27-xxx range.

I have the registrations for Botswana, Kenya, New Zealand, South Yemen and most of Ecuador. Still need the registrations for Kuwait, Oman, Saudi Arabia, Singapore and Sudan.

Any help would be appreciated.
