Creating a font with fidelity to Stokoe's 1960, 1965 documentation.
These letters look like they were made from an architectural tracing template.
Update 2021-02-26: This appears to be a typeface called Upright Gothic. Appears to have roots in 1910s? 1940s? 1960s? engineering architectural lettering templates with any combination of the words 'vertical' (vs. 'slanted') 'single-stroke' 'mechanical' 'single line' 'commercial' 'gothic' 'capitals'
## Stokoe samples Unique figures: - slash-zero (similar to ร but using a zero, not an O) - flat/straight top 3 (https://www.fontshop.com/people/stephen-coles/fontlists/flat-top-threes)
