I have an unbuilt, mint BH Models vertical cylindrical water tank kit available, black plastic. It is based on a Santa Fe design, but similar tanks could be seen anywhere on railroads or industries. The tank is 24 HO feet in diameter, and can be made up of one, two or three vertical courses, giving a height of 29 feet, 43 feet, or 60 feet. It has a flat roof (lid). An added feature is that I bought an extra roof (lid) for it that is conical, so you can choose the lid you want, or actually make two separate tanks using one or two courses on the first, with the third on the second tank, using both lids. Whatever! The tank does have a ladder and a decal for the volume indicator. The tank kit cost was $19.95 plus $3 for the extra peaked roof lid, $22.95 total. I'll send it to you via Priority Mail for $19.00 total. Nice tank! If interested, let me know via PM to meteor910. Thanks. Ken
