Switchable weight plates

Here I have a weight for the three-point shot with shiftable weights plates. Basis weight 500 kg 6 plates switchable per plate 200k, total weight of 1700 kg.

Color plates selected.

Idea comes from the JD-weight from LS 11 of dada. I have all the parts rebuilt. Who was the Urskripter, I could not find out.

Have fun
