The largest collections of historical artillery material are in numerous and often world-renowned public museums, many of which I have visited. However, I was only able to find three examples of a serious scientific catalogue of such artillery collections. Originally, many of these museums represented national status in the 19th-century competition to prove itself as a 'cultural nation'. At that time, the museum employees were interested professionals in science and research with respect for the collected objects, the museum was a scientific window for the general public. Today, these 'professionals' are mostly just public employees of a state agency with a similar mindset and corporate culture. Over the decades, my experiences in many museums and countries with inadequate inventories and questionable identifications of artillery objects have accumulated. Technical knowledge of artillery is mostly minimal. The artillery objects disappear from the exhibition to the depot, and research and information about artillery in particular was sometimes even forbidden. A correspondent even mentioned that the search terms 'weapons' and 'artillery' were deleted from the search index of his public library. My visits and research were mostly tolerated with professional courtesy and helpfulness. To be fair, it must also be mentioned that I am not aware of a single course or seminar that imparts specialist knowledge of artillery. Unfortunately, my rather negative personal perceptions of museums were repeatedly confirmed by inquiries from all over the world. These were often justified by the explanation that the local and even national museums did not respond, they had no knowledge or interest in historical artillery.
