Siemens PTB55TLN

The following pictures were taken in Whitehaven, 2006

As can be seen from the above pictures the lanterns appear to be running a 35w SOX lamp. The lanterns can run either a 55 or a 35 w lamp. When I first spotted these lanterns, I thought they were a big version of the GECZ5713. So I was quite surprised to learn that they were made by Siemens. I obtained my first PTB lantern on the 26/04/2007. Since then I have added another two of these to my collection thanks to Paul Turnbull. The following picture is of my PTB55TLN
