Thank goodness I’ve got a card catalog big enough to log and cross-file a couple hundred models. I’m thinking of categorizing by manufacturer, by decade, and including typeface samples, which I’ve already been doing as I add them to the typewriter database.
I remember chuckling when I saw Tom Hanks’ tags on his typewriters. Now that I’m over 15 of my own which are constantly out and about the house, I realize the benefit of matching tags on machines and their cases. I don’t have an issue with identification and matching (yet), but if nothing else, less interested family members can properly store them out of the way if they need to without causing issues. Interested visitors can also get a quick précis of machines they run across.
