ELECO GR 553 (Gear In Head)
The ELECO GR 553 was part of the second wave of plastic refractor, gear-in-head lanterns. By taking
advantage of the new, smaller low-pressure sodium gear which was developed in the late 1960s, it allowed ELECO
to design a smaller canopied, more streamline, gear-in-head lantern.
The GR 553 was specifically designed for top-entry tungsten/mercury conversions where space for gear in the column
or elsewhere was limited.
This lantern stood somewhere in Northamptonshire and was removed by Darren in 2008.
