Is Bowser still producing the Selley line? Despite the fact that I do admire water tanks, I'm enough of a realist that on the modular layouts I run on and on the modules I do plan to build, there probably isn't enough room for a full-dress water tank to service my or other club members' steam locomotives. There does tend to be enough room for water columns, though.
If Selley has been discontinued or if Bowser has only dropped the water columns, who else makes O scale water columns these days?
