ellenbr, There is nothing on the gun that says its a "Luck Suhl" or "Chase Gebrüder Luck Suhl or Simson & Luck Suhl" only C. Adam in Coln A/Rh. The reason it was believed to be from Luck is the imperial eagle with an "L" on the bottom of the buttplate, even though it looks like and "X" or "K", and the two marks on the barrel with the crown over a distinct gothic "L".
