This company appears to have had two names simultaneously from 12-Aug-1991 to 05-Mar-1992:
In fact, the filings show that it was incorporated as “NEXTLAUNCH LIMITED” and changed its name on 05-Mar-1992 to “CHELSFIELD PLC”.
Please correct this, and please do a global search for any companies in the database that had more than one name simultaneously, as that is legally impossible.
