Hi,
a passport is a problem, photo is too small Resolutions, larger letters to blurrier. To post you can attach a picture of the maximum size of 500kb, it is not enough to increase. I'll send you a private message, my email address. Then send me a scan of the document in very good quality, will come in the mail to 25 Mb.
I have an idea who is well read. I have a friend the historian, works in one of the archives in Bydgoszcz. I think that the document that was created in Bydgoszcz, should be some trace in our archives. I know that the Prussian officials to draw up each document indicate this in their records. If these documents have survived, you can confront with them a passport. I think I survived, of Bydgoszcz, although fighting took place in 1939 and 1945, but without the use of heavy artillery, so the city was not destroyed.
Using state archives in Poland is free for citizens. You only pay when you want to archive workers to seek for us. You can look for yourself for free.
The plan is to:
1. Send me a high-quality scan
2. I'll check the traces of this document in Bydgoszcz archives.
3. How will we know exactly what it was called, it only can be found in the documents from Witkowo.
My friend the historian will not want problems to help. He also likes puzzles and mysteries. How to find something specific, it will set him a bottle of whiskey, which we drink together.

In Poland, more difficult to arrange something for the money, the easiest way for a bottle with friends.

Greetings from Bydgoszcz
Slavko
