A Z9574? Never knew such a model existed! Full of surprises GEC eh? ;)Re: The Eleco GR200 / GEC Z9574 (180W SOX).
I was interested to read about the above Eleco lantern, also being a product of the GEC. Anyway, I came across this leaflet whilst having a sort through my old streetlighting bumf, which does indeed prove such a product existed or was at least publicised! Although there is no date, I would suspect it is late 80s, as it indicates 131W SOX-E lamps. Was this simply "badge engineering" or a case of producing under licence? Whilst slightly off topic, Manchester Corporation were huge users of both the iconic GRs and Revo Hyperions, especially in conjunction with their new "standard" column of the 60s - the hexagonal Adastra from "Poles Ltd". These were to be found on the majority of Group A roads, mainly replacing former MCT traction poles. In the name of progress however, all these "new" installations were swept away by the Amey PFI around 2007. It is fair to assume that subject to the purchasing policy of the council, some of these GR200s may well have been of GEC heritage.
