"As for the maps, with all due respect, if you actually knew how to read them, you would understand why I think the bells are so important."
Many people believe they know how to read the Stone Maps. Nothing unique in that belief. As for "all due respect"......I believe you have addressed that issue a number of times already.

I have my own doubts about your bell expertise, as the Sky Harbor Mission was a no-brainer for anyone who has studied the Spanish mission system. Those doubts and five bucks might get me an average cup of coffee.

The wedding chapel was "open air" and placed there so people from places like California/Hollywood could fly in for a quickie marraige and fly back home with little delay. There was no other reason for it being placed where it was. As it turned out, less than 50 weddings were performed there.
The general shape of the bell is the only thing that can be discerned from the picture you supplied the site for. I have quite a few pictures of missions, and many of them show the bells. No one has asked me to do any research for them,

You seem to have some strong opinions of the Sky Harbor Mission bell, so it would be interesting to know how you think it might differ from the San Miguel bell you are going to research.
