796 gram
Marked with an "Z" and an old "LB" sign
The "Z" means maybe "2" but I am not sure.
"Z" could be also "Celle" or an other sign for a town or country

I am sorry that I can not identify the other four marks...
With some fantasy I see an eagle or an tower on the right top mark.

So at this time I would say 2 lb of 398 gram !
