Unless I am mistaken, you did not include the following publication
Dziennik Komisarjatu Rządu na M. St. Warszawę. ( in the years 1920's ) available with OCR on polona.pl
It contains big lists of persons (with addresses) who lost their passport or other official papers.
I have found useful information there: I am doing the very fastidious task of looking for all ROTENSTEIN /ROTENSZTEIN/ ROTENSZTEJN on polona.pl ( answers by hundreds)
Request that a source be added to the Genealogy Indexer. Include a brief description of contents, with as much of title, geographic scope, date, and organizational structure as you know. If the source is already online, provide a link.
