I think it would be hard to sum it up much better than that, whether speaking of older blades mounted for the war, gendaito, or simply mass produced gunto. For good or ill, these items were made for and accompanied these swords through an extremely significant time in the worlds modern history. If for no other reason, this should guarantee them a measure of respect from anyone interested in the blade that resided in them for a time, even if they have no interest in such things.
This discussion caught my attention since at the moment I'm taking a break for a few minutes from working on a WWII era Gendaito. This blade has had an appropriate shira-saya made and thankfully the present owner did recognize the significance of the mounts and choose to have a tsunagi made and keep them with the blade as they should be. Certainly the sword need not be stored in or even displayed with these mountings, but while it is not of any artistic value to keep the war mounts, it is certainly of historical value as well as a part of the swords history.
