Hi Roy,Phil, Fred.
Roy,thank you for posting the link to the gas lamps in Malvern, I'll have to get over there when the snow is around and get a few pic's as the view would be like any of the old streets of Birmingham of the past.also I liked the clips of film relating to the workings of the timer of the old gas lamps,I like the cast alloy body of the unit with the brass gas valve activation mechanism,I wonder if they where ever manufactured and assembled in Birmingham?
Phil, the only conclusion I can come to relating to the height
of the lamp post,is of whatever type bulb is fitted be it florescent,halogen,arc or the new LED is to give maximum ground area illumination.
Fred thank you for posting the pic.
