Gary,
I don't know that projection or the specifics with your tfw. This
website might help you research the projection and get the proper parameters.
I'm not sure if this is the projection that you are after but it is similar.

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.
Gary
