JU88 W/n 4081 8/KG30 and w/n 3223

[ThreeGreens]

Does anyone have any history on the above aircraft?
I understand that it was damaged in combat 8th Oct 1940, but returned to its base in Eindhoven.
It was lost at some stage later over the UK, but have nothing further.
I have a plate from it that reads :

Baumester RS.4
Werk Nr 4081
Anf. Z. F128018

Can anyone decode this for mas well?

Is there a publication that allows german plates to be decoded out there?
In addition, does anyone have any information on a JU88 with information on a plate as follows :

???rat Nr 9-211 J-1
Werk Nr MZK211 H-1 3223

Whilst looking at German langauge, I have a red plaque that reads :
Dachabwurf
gesichert
entsichert

Can anyone tell me what that means in addition?

Many thanks
Graham

Dachkanzel = Cockpit/Cabin Roof

gesichert = locked

entsichert = unlocked

Probably refers to the unlocking mechanism for emergency escape
from cockpit.

bye, good luck
