How true. Museums are very limited on resources. I've maintained that most museums survive because of volunteers. Even curators at major museums have their shortcomings. I once spoke with the Smithsonian's Chief Curator for firearms and in the course of the conversation learned I had more expertise on one narrow subject matter than her. She was getting angry when I told her their website isn't quite right and I apologized said let's do this by email. By email another Smithsonian curator told me that a false muzzle was a type of suppressor. I suggested he look at the pictures in Bill Edwards' book, Civil War Guns, that showed John Amber (dec.) using one to load a target telescope rifle. Lessoon: A PhD outside of their area of expertise is a layman.
Museums need to have good libraries to enlighten the curator and to helps him/her interpret the object, educate the docents and curate the displays.
BTW, that chief curator isn't working for the Smithsonian any longer and for a while had a column in the NMLRA Muzzle Blasts Magazine. She was there at the time The Patriot was being filmed.
