Nope. That company, which by the way is not "Lohr Lauer Nurnberg", but rather "L. CHR. LAUER NÜRNBERG", named for its founder,
Ludwig
Christian Lauer, who founded it in 1848, made lots of military insignia, signage and other finished metal doodads for the postwar U.S. occupational forces. After all, Bavaria was in the American Zone, and they were always desperate to find ways to keep the locals somehow gainfully employed.
The company is still in business, though no longer located in Nürnberg (which you might know as "Nuremberg"). Instead, they are in the nearby town of Röthenbach an der Pegnitz. Currently their website at
www.lauer-metall.de just gets you a big blank nothing, but here is their old-timey contact info:
L. Chr. Lauer GmbH
Sulzbacher Str. 47
90552 Röthenbach
GERMANY
Maybe a letter to them might reveal more details on the object. Otherwise, I'd try posting images of it and that better condition eBay twin of it to various Militaria forums,
like this one.. Sooner or later someone will recognize the unit insignia.
