Hey good to see you Jim!
I think you’re correct about it being Austrian. I’ve run across the same setup before in Austrian clocks. Sorry to say I never figured out a way of letting the springs down other than to put some fresh oil on the pivots, pull back anchor and fly (if adjustable) and let it slowly run down. If I remember correctly the clicks are attached to the inside of the main wheel. Could be wrong about that so please let me know where you find them. There may be a way to let them down but I never was able to find any small hole along the circumference of the barrel to insert a pin or something to release the clicks. Weird design huh?
Well good luck and please let us know what you find out.
Aloha for now over there in paradise Jim,
Bob
