Axel on Louis Kebler and the script L:

"This mark was used by the Gebrder Kelber barrelmaking company, founded by Louis Kelber( Trbenbachstrasse 1 at some point ) in 1894, owned then by Louis, Robert and Wilhelm Kelber. They used either this L stamp or a LK. In 1927 the "Gebr. Kelber" company was dissolved, but as noted above both Louis and Wilhelm Kelber started again on their own, Louis using the "LK" stamp and Wilhelm the well-known "WK". Who, one or both?, for which orders?..."

It would seem that post WWII that the heirs and assigns of Ernst Kelber were Karl Kelber & Alfred Wolf and they carried the firm of Louis Kelber forward. I'm not sure if Ernst Kelber was the sohn of Louis or not. For sure much more research needs to be performed in the area of Gebrder Kelber.

Kind Regards,
