Hello, I found this cuckoo clock that is missing it's weights, pendulum and crown. I've gotten various suggestions for the correct weights to buy and the length of pendulum. I'm hoping for some additional assistance.

The movement is marked GM 1884288 1892176. Regula 25-P. Made in West Germany. A. Schneider Sohne

From what I've found on the internet I believe this was made in either 1982 or 2002?

Are two 275g weights for the movement and 1-320g weight for the music box and dancers sufficient? Or do I have the weights wrong?

Thank you!
