Im not able to see the pictures on that website without a profile. I read through the article and thread you posted and it was very informative. I also found an earlier thread that mentions a similar action. I greatly appreciate the quick identification.

Did some google digging as well and found a Christoph Funk that has a very similar action and barrel style but with a tang safety
