Atlas Beta 5 Top Entry Metal Ring

The picture below is of an Atlas Beta 5 on Cheviot Road in Carlisle. It was taken down in 2010.

The photographs below show the lantern. The thing that interested me about this lantern was the bowl and the mechanism for holding it.

As can be seen from the above photographs the Bowl sits inside a metal ring. I believe that this was the first incarnation of the beta5.
