It was made in Suhl by Bchsenmacher Franz Luck. The "Reichsadler" or Imperial Eagle with an circled L inside on the toeplate, was the trademark of Luck, Mhlplatz 4, Suhl. The concern was founded in 1847 when Franz Luck hung out his gunmaking shingle. His son Karl August Luck & grandson Wilhelm Edmund Luck (1857 - 1910) took the reins & continued for a time. The Crown over Fraktur/Gothic Letter(possibly L) may be the mechanic who brought the tubes to the state of completion. It would seem tha the lower tube was sourced from the Schilling forge. I have my doubts it was made in the 1870s. What is the weight of the drilling, 5-Pfund-Drilling?
