Tartan ... you could always make it a pet project ... and start diarizing them, like I have with the acronyms and definitions. I'll be posting an updated thread as the list has grown considerably from the first.
I'm sure many would appreciate you doing so.
As a starter ... here's what I'd envision ... a list of the model numbers in numerical/alpha order then a list of definitions and manufacturers listed with model numbers.
15-91 ... Vintage Singer
440 ... Bernina
6600... Janome
7700 ... Janome
12000 ... Janome
DC 3050 ... Janome
etc. etc. etc.
~~~~~~~~
Bernina ... 440 (and list of models)
DSM ... Domestic Sewing Machine
Janome ... 6600, 7700, 12000, DC3050
Vintage Sewing Machine ... with a definition
etc. etc. etc.

Go for it Tartan! You'll have fun doing it and learn a lot as you go.
