A gentle approach to the hoarder term, both with and without a connotation tone; gentle as you usually are, Jim. But allow me to add a humble note to the collector categorization, as an apendix to the implicit subject.
Collectors, to be collectors, do not have to follow any specific tendency. There are those who enjoy learning how the weapon was used, in what context, their origin, what would be their date, that is, the quantity of juice they chose to squeeze out of available data, easily or intensively (re)searched, depending on each one's disposition; however not necessarily interested, as an allien example, in what is the composition of metal each weapon is composed with, to the extent of studying the temperature at which its material melts ... if i make myself understood. Nonetheless collectors still they are. Let us make sure that collectors out there who are not interested in ultimate academic details are not as vulgar as hoarders; they simply might not take it so flattery
