Hi

On wikipedia, there is a nice table listing the distribution of known Ulfberht swords.

However, this table does not show the spelling, most notably

Code:

+VLFBERH+T

vs

Code:

+VLFBERHT+

(but I seem to remember more variations exist), use on those finds.

Does anyone know of a source that lists the distribution of Ulfberht swords, that also lists which spelling variation were found where, and from which period?

Ingo Petri has written a good paper called "VLFBERHT swords: Origin, material, and manufacture" in 2019, I got it from academia.edu.

Furthermore the paper "Hypereutectoid steel in early medieval sword production in Europe" by Paweł Kucypera and Jiří Hošek I also remember touching on the subject though it has been some time since I looken at it.

This thread covers the subject fairly well.

The analysis done by the Institute for Inorganic Chemistry at the University of Hannover is pretty conclusive. We can say with a fair degree of certainty that Ulfberht was a Frankish smith working in the Taunus region in Germany (most likely in either the Lorsch or Fulda monastery).
