I love hearing the differences from the different styles and ages of mics. I wonder if these are in working condition? Having a sample recording from the various mics in the collection would add a lot to the site. Maybe not every single mic, I'm not trying to be greedy, but at least one from each style and pick up pattern.

In the category of unknown pickup patterns, I wonder if maybe they are not in working condition as it seems like it would be a matter of testing them to determine the pickup patterns.
