Things that have disappeared from our town landscape - gasometers.We used to have two at the bottom end of Leamington, I remember them from my childhood. Now the site is under housing, although not until the top metre of contaminated solid was removed as I recall.
For kidz who don't remember these things, in the middle of the ring were three segments of the giant plunger affair which stored gas. The more gas, the higher the plunger went up until it reached the top. It's a clever arrangement and for a certain era - iconic. The move to natural gas and introduction of a national pipe network rendered them obsolete, but moves are afoot to list those that remain.
I was reminded of this when looking at the view from Ally Pally a few weeks ago. Then on the run back, there was another holder frame for my passenger to photograph. All very interesting.
Modelling these from scratch would be a bit of a nightmare, but in the era of laser cutting, technology have come to our aid with kits such as this Modelux OO version.
For traditionasts, Bilteezi made a cardboard kit, although it doesn't look right to me. More like an oil storage depot.
Hornby used to sell a respectable ready to use version. You can still track these down on eBay.
I'm sure someone has made an etched brass version too, but can't find details at the moment.
