Davis PT1044

Lantern acquired in September 2006.

Thanks to Davy Warren for providing this lantern, which apparently saw use in the Brighton area. The PT1044 is not a lantern I have encountered before - it is in the shape of a Victorian gas lantern; however, the only lanterns like this in the Derby area are DW Windsor 'Windsors'. Further afield, examples existed around Chesterfield Town Centre, however.

 

The lantern has an aluminium frame with a plastic canopy and glazing panels.

 

To gain access to the gear and lamp, the canopy must be removed. The decorative finial unscrews and then the whole canopy lifts off.

 

The canopy is not sealed and so damp can enter the lantern quite easily - notice how rusty the ballast's core is. To replace the lamp, the centre plate must be first of all be loosened. The supply cable would enter via the small grommeted hole to the bottom of the picture. The hole is shared by the base casting's earth wire.

 
 

The PT1044 was mounted to a miniature column on Friday, 18th May 2007. A SON-E lamp was fitted in place of the SON-T as I felt that it gave the panels a more diffused appearance.
