The Philips sgs201 was a popular lantern in the UK. They have a GRP canopy and a polycarbonate bowl. They could run SON/ SOX/ MBF lamps.

Staines

This Philips SGS201 is in staines. It has a green Royce-Thompson photocell and it runs on a SON lamp. Sadly, it does not work and I think it is owned by Spelthorne. 
the bowl is quite clear for its age, but the canopy is not as clean as the bowl.
