How do I get a QNH (for free) concerning 10 years ago ?

[Arvidius]

I am looking for a source on weather data about a specific day in 1991 in Belgium.

Through the KMI (Belgian national metereological Institute) I can retrieve this information, but it costs ...

Can anyone tell me where i could get this information for free?

In particular I'm looking for the (local and regional) QNH on the 18th of august 1991, roundabout 18.00 hours Local Time (16.00h GMT / Zulu / UTC) in the airports of EBOS (Ostend); EBAW (Antwerp); EBBR (Brussels) end LFQQ (Lille, France)

For people who do not know this abbreviation: QNH is the barometric pressure (in millibar or Hectopascal) reduced to sea level. (in dutch : luchtdruk op zeeniveau; in french : la pression d'air au niveau de la mer).

Thank you.
