I'm trying to find the unit history of the IR23 that came out a year BEFORE the first world war. The book is called '' Geschichte des Infanterie Regiments von. Winterfeldt (2. oberschlesisches) Nr.23 E. S Mittler & Sohn, 1913 '' It came out in 1913 and im having a hard time finding it. If anyone has a digital copy or PDF of this book and is willing to share, it would be much appreciated, if you pm me i can give you my email. Attached you will find a screenshot from a catalogue where the book's title appears in. Many thanks!
