I have a broader question to pose. In the early 1970s, Joseph Baier published a series of articles in the Bulletin on Matthias Schwalbach. One of the articles included a table of clock towers where his clocks were installed, and the status of the clocks at the time. As part of a presentation I am planning for my chapter, I thought it would be fun to update the tables.
I have been contacting individual churches, but I thought I would also reach out to collectors. What I would like to do is to 1) create a table that indicates if a movement is still present, has been modified, or been completely removed, and 2) find out if any of the removed movements are still around. I do not plan to create a table that says "this movement is in the collection of so-and-so", rather, to just say the movement is in a private collection.
