[Ger-Poland-Volhynia] Bleschke- Einwandererkartei, 1939-1945

[Vera Miller]

I am trying to find Bleschke on the Family History Center's microfilm for  Einwandererkartei, 1939-1945. I have already looked under

Blazinc, Karl-Blechner, Elisabeth
Vault INTL Film
1806225 

Blechner, Elisabeth-Bletsch, Berta
Vault INTL Film
1806226 
I saw on http://sggee.org/research/AlternateSurnamesDatabaseSubstantiated.pdf that Bleschke also can be spelled Bleszko. I did not see any entries for Bleszko.
Does anyone have any suggestions how to find this name on these films?
Thanks,
Vera
