Question regarding Patrone P318 drawing


#1

Could somebody help me to read the inscription underlined by the red?
I can read only “[b]Lieferungsn/b [b]u/b” and the last word is hard to understand for me


#2

It says “Lieferungsnummer und Ratenbuchstabe” what translates to “Lot number and sub lot indicator (a letter)”

Thank you, Alex!
