Too, Simson & Luck were most chummy. Karl Luck was a sidekick to Löb Simson & Moses Simson, who collectively hung out their gunmaking shingle in either 1850/1856. Simson had a hammer forge and I am not sure how technician Karl Luck was tied to Gebrüder Luck, but Gebrüder Luck was know for gun parts as well as something to do w/ Electrical Power facility? Anyway, I do not see Karl Luck as a Büchsenmacher, but he still could have been. Karl Luck along with Löb Simson & Moses Simson joined forces in 1862, the same year Löb expired. Then 7 years later in 1869 Moses expired. Karl Luck hung on till 1884 and left. So I am sure there wa a lot of cross-sourcing between Luck & Simson. Both went on to make weapons & bicycles and Simson dabbled in cars & Rubber Baby Buggy Bumpers.
Back to Luck, the made what was referred to as a >>5-Pfunds-Drilling<<. It is entirely possible that someone sourced components from Sauer & Luck and made this drilling during WWI or that Luck made it?
