For the e-libelle modification it has to be as light as possible.
I've reviewed 7 w&b bulletins so far and evaluated their damage history.
If one throws out those lead batteries we'll get to 206kg but not below 200kg... The average is about 215kg, no real correlation with repairs.

Weighed SN 470 last month: 200.8 kg
