Hey Peggy, I just got back from a mission trip with the youth in our church and saw your post. A cheap source for Hermle movements can be found at most thrift stores. I see them all the time. Most of the cheep key wind clocks you will see have hermle movements. I find that most of them, once cleaned and oiled will run. Just make sure you take pics. before you take them apart. Also when putting them back together, take care when placing the plates back over the pivots. Then tend to brake easily.
