Here’s where I start when trying to identify the typeface on a Smith-Corona typewriter, and where I’m most successful in getting an ID. This PDF got passed to me almost a decade ago, but I’m not sure from where. Sadly, it’s a very dark, low-contrast scan, and not much can be done about it. The original PDF is scanned at very high, very fuzzy resolution, and for that reason isn’t hosted anywhere I know of – but I have downsized the scans for web-friendliness and made them as sharp as I can.
Wow! I wish all companies had such detail of their type faces. I see they even have a Radio Gothic which I think is the same that was used on the Corona Mill, but the Mill has a slashed zero.
Why doesn’t it have Numode?
Because Numode wasn’t around in 1954, mos’ likely.
