I have just received my copy of this anniversary booklet, which was reviewed in the recent number of the ECRA Journal. I find it most interesting and excellent value for its price of 10 euros (about $14, £8.50), plus postage.
It is written in both German and English so there are no translation problems, and is a 150 page detailed account, with many photographs, of Hirtenberger’s history, from its formation from Keller in 1887, through its time as Gustloff Werke AG, up to the present day. It concentrates largely on its ammunition production with details of manufacturing processes and cartridges produced for home and export, with illustrations including cartridges and cartridges boxes, and headstamp details. It also gives some account of the firm’s activities in other fields, eg various munitions and even aircraft.
Email: firstname.lastname@example.org for details of postage charges, and to order (I used paypal).
amended once to correct typo!
