Some time in September 1990 prior to 13 September 1990
According to the HOLMES statements of Henderson (S4710J), Williamson (S872BS)
and John McLean (S5320I) during September 1990 they learnt that MEBO in Zurich
had been identified as manufacturer of the Togo timer K-l (DP/84).
Henderson’s statement says this was discovered “following extensive inquiry”.
There are no further details in the HOLMES statements or police report about how
the connection was made.
This issue is addressed in chapter 8 of the statement of reasons.
