Reproducing only one of anything would be highly unusual so if it is a repro, there should be others. Conditionwise, I have original US military manuals well over a century old that are in similar appearance.
Found the forum. Thanks!Originals not on clay-filled (super smooth) paper and IMO should exhibit some rust on staples at this point. Repros still available. As I recall it, originals in tan covers. Recommend you ask on the Luft. drillings forum on Still's Luger Forum where the specialists are.
Does anyone know how to put up a post on the Still Luger Forum?Found the forum. Thanks!
