Hi Dave,
If it is a Schiedmayer, here is a manual from the class they gave at Norfolk this summer. That's really the only current manufacturer, though Yamaha makes something they call a celeste with a grand piano action (upward striking rather than down, and much narrower tone bars).
There are a lot of varieties of older instruments still kicking around. Mustel was the original French inventor, and there are quite a few of those. Jenco, a US percussion company, made a lot in the mid 20th century. I have done a fair bit of work on one, and described it in a thread here. I have also worked on a Mustel about 20 years back, but didn't take photos. It was more similar to Jenco than to Schiemayer.
Hope that gives you a start, at least a hint of what you are facing. "Broken key" obviously just means non-functioning, and there are lots of possibilities. A displaced spring could do it, but whatever it is, it should be fairly obvious. They are different from pianos, but analogous in enough ways that it is just a matter of observation to find the problem.

Hi, David.
Thanks for your reply. I don't have that but will try to get it.
Not sure they will know either, as I think it is being brought in
for the series and may not arrive until I am scheduled to be
there.
