[gdal-dev] Projection for OSGB36

I have a series of OS map TIF files with associated tfw files.  However,
the tif files contain no information about the projection.  I understand
that these files are using OSGB36 AIRY1830

 

Can anyone tell me the precise text specification I need to be able to
set up this projection.  

 

An example tfw file is:

2.5

0

0

-2.5

215000

254000 

 

I tried to importFromWkt with the string from the gdal/data/ecw_cs.wkt
but this did not seem to work.  I don't believe that OSGB36 is one of
the WellKnownGeogCS either.
