J. A. Kluge, Horní Staré Město

The extant records are important sources for the history of flax industry in the Trutnov region from the period of the First Republic and the German occupation, but often also have a wider import beyond the region. They document the use of Jewish female prisoners and POWs as forced labour at the J. A. Klug Company's plants. Invoices and bills of lading from 1943–1945 have been preserved almost in their entirety; these can provide evidence of the company's business relations and of the deliveries of products to customers during the Second World War. The fonds contains photographs of the individual factory buildings where the prisoners worked. It also includes a diary with entries on important events and visits to the plant in Temný Důl, which provides interesting information.

The fonds is arranged as follows: A) Company management and administration B) Employees C) Accounting and reporting D) Documents relating to buildings and technology 1) Construction documents 2) Technical documents E) Photographs F) Samplers.
