The "Reichsadler" or Imperial Eagle with an circled L inside on the toeplate, was the trademark of Luck.

Gebrüder Luck & Sauer may have had a close association, but the script Ls are not exactly the Fraktur Ls used by Gebrüder Luck, who was a business partner with Simson in 1880 I believe it was.

So still not for sure on the single script stylized Ls.
