* How is it filled out? It's a horizontal document not fitting in type writers of normal format. For that reason what I do is type it all up on a normal sheet of paper (on a standard German WW2 typewriter), scan it with very high resolution, then locate it on the document in the right spots and print out. It's a laborous effort, but guarantees the closest possible result to original typewriting without having a large format period typewriter.
