Andy;

You may very well be right with that one.

When I posted these three drawings, I had real doubts as to whether or not we would get any closer to an answer about what these drawing are for...yet I still thought of them as interesting none the less. Looks like we are making some progress.

These are no doubt early sketches. It will be interesting to compare them to the final blueprint plan, (whenever I get it back), to see if they correspond to features in the final plan.

Are there more ideas, or more agreement with the ones already put out?
