You should really enjoy this from April 1945 then:

CX/MSS/R534(A)
1. From PNOPI ((III./KG)) 76 HEBJI ((C% Abt.)) (Roman)I – T signed Burgart Obltn. and Technical Officer to QMG. Director of Supply Berlin – (smudge), dated 19/4:
(Smudge) communication of FOBEZ ((OKL)) QMG (Dep. III) dated TEFOF ((15/4)) ((45)).
1) 5 ZINN ((Ar 234)) ZAHOD ((C% 140)) ZIHRA+
ZAHOD ((C% 140)) ZELVE+
ZAHOD ((C% 140)) ZEVIA+
ZAHOD ((C% 140)) ZAINS+
ZAHOD ((C% 140)) ZEELY+
2A) 1 ((Ar 234)) ZAHOD ((C% 140)) ZEICA+ on TEDIK ((10/4)) ((45)), burned out as result of bombing attack, damage ZABAL ((100))%.
2B) 1 ((Ar 234)) ZAHOD ((C% 140)) ZEVEL ((C% 476)) shot up by fighter, belly landed and sustained 60% damaged.
A) 16 ((Ar 234)) B-2.
NOTE: 1) + These Nos. not known exactly, evidently Werk Nummern.
2) Possible interpolations of above pro-forma:
1) To strength.
2) A) [and] B) Off strength.
A) Total aircraft.

I don’t know of a full list of these Z codes. Bletchley didn’t have enough examples to crack the whole system before the war ended but the letter groups do run alphabetically. Some of the identified ones still carry a question mark. Based on the list I’ve compiled:
ZAINS is between 144 and 150
ZEICA is between 326 and 330
ZEELY is between 300 and 324
ZELVE is between 375 and 380
ZEVIA is between 460 and 500
ZEVEL probably isn’t 476 because 140476 was 8H+DH of 1.(F)/33, captured intact; it’s somewhere between 460 and 500
ZIHRA is somewhere between 575 and 600
