Here's the model with 1 iteration of Turbosmooth.  Only 3100 polygons.  Yours is next to it, with well over 30k polygons.  Of course, I could go in and chamfer some edges, to sharpen them up as you have in your model, but even with several chamfers, bevels, and anything else I could think of to make it exactly as yours, our new model will still be thousands of polygons less heavy, because we've been able to completely control the flow of edges to create the profile of the object, from start to finish, using this technique to create it.  I'm sure there's other ways to create it as well, which are just as efficient, but this is how I would have done it.  Total modeling time here was probably half an hour?  It was a lot faster than the time between my posts indicates, because I was obviously doing screencaps and uploading at the same time.

Hope this was helpful in some way.
