Paul,
Meteors were of 327 Squadron, Soesterberg Airbase.
There is a local story here
https://gaanenbeleven.nl/de-gloster-...an-baarn-1952/ (date is incorrectly put in October 1952...) whereby Groenendijk is in "7E-4" (I-135) and De Nijs in "7E-3".
According this (I think more reliable) website I-136 was "7E-
5". See
