Yes you could be right 40 years is a long time to remember all the 
details.  I know the first one was a Ferranti Mercury but I'm a bit hazy 
about the immediate 48 bit successor.  This was at Univ of London.  I 
did not survive long before the IBM 7090 was installed which was much 
more reliable but required a switch from Mercury Autocode to FORTRAN 
although an Autocode emulator called CHLF3 was written for the 7090.

Yes a quick google confirmed that in addition to UMIST, UofL and BP had 
Atlas' computers.
