After my business trip, I am finally able to continue the story about the rubber company.
As I've mentioned in my last post, the company in question was founded in 1856.
In 1870, a company producing similar goods was founded in an another part of the region and took over the "Rubber-Comb-Company" in 1929.
After the war, the facilities of the new parent company were almost completely destroyed, so soon after the war the production was relocated into the buildings of the subsidiary.
The rubber combs produced in this facility were appreciated by hairdressers worldwide.
