There is a excellent picture on the internet for the original handwriting of kyrie Gott Vater in Ewigkeit as found in the 1537 Naumburg hymnbook: http://www.pt-magazin.de/de/app/media/resource/_ing12z30.deliver

The present picture appears to be from a 1959 reprint (reprinted in an 1996 essay reprinted in a 2001 collection of writings of a emeritus professor at Sorbonne). Maybe the photograph is not in public domain, but the owner is listed and can be contacted.
