Translation:

Egr. Gentlemen
first of all a huge THANK YOU.
I must therefore be able to think:
- that my Stutzen was made in Suhl by the gunsmith Richard Schuler, assisted by Wilhelm Kelber?
- that, also, with some reliability can still be attributed to "Peterlongo" given the friendship of Schuler with Marholdt?
This last hypothesis, since there is no concrete "officiality" (signature, acronym, etc.) would push me to accept more paternity (which is what I was looking for and interested me) Schuler also in the light of a possible commission by Peterlongo / Marholdt.
I hope that with your lucid, passionate, competent speeches I can put the word END to my research.
Research that without you everyone would still be poles apart.
A hug.
