This is an older type... Wellhead. (again, thanks to Ken )
The first pic is the original that I am using as a guide. I have no dimensions to work with except that it's approx. 15-20ft tall so I am eyeballing the heck out of this thing. Some of you with sharp eyes will notice a lot of proportions are off and some details are missing. Some of them are going to stay that way.
What I'm learning the most on this exercise is work flow. And boy, am I learning a lot. (but grammar isn't one of them ) I would like to give credit to http://www.martinrinehart.com/models/tutorial/tutorial_toc.html for really helping me to understand work flow better.
The following pictures are the progress.
