Rolf-Jürgen (aka "Hiltibrant" in the german UhrForum), donated some very interesting additions to the archive:
In spring 2017, he donated another three movements to the movement archive. From two of them, there were no other movements yet in the archive: Enz 153 SC, Reconviller 12 and a Bauer 10 1/2 new, and also two Ronda movements, a caliber 1017 and a caliber 1215.
The next donation was then a Felsa 465N, on which the balance staff was broken, but whose mainspring helped, that there's now a working specimen of this movement in the archive.
Only a few days later, another donation was sent to me - a Förster 51 with a few missing parts. I'll see, if I can find them in the few boxes of (mostly) unsorted spare parts:
Thank you very much, Rolf-Jürgen, for supporting the movement archive!
