[Proj] PROJ.4 parameters for EPSG:3053

[Jean-Claude REPETTO]

Hello,

I am looking for the projection parameters of the Hjorsey 1955 / Lambert 
1955 projection (Iceland).
The epsg file shipped with PROJ4 contains this warning:

Unable to translate coordinate system EPSG:3053 into PROJ.4  format.

I don't know the reason of this warning, may be it is because the LCC 
projection is west oriented ?

Are the following parameters correct for this projection :
+proj=lcc +lat_1=65 +lat_0=65 +lon_0=-18 +k_0=1 +x_0=500000 +y_0=500000 
+ellps=intl +towgs84=-73,46,-86,0,0,0,0 +units=m +no_defs
?

Does anybody know sample maps or GCPs using this projection, to check 
the parameters ?

Thanks for your help,
Jean-Claude
