Hello, this is an interesting one. It appears to be nearly identical to a font in Monu-Cad called “Bold Roman 1”. However, it seems to be a somewhat better version overall. While they both share the same weight, serif thickness, and a very narrow numeral ‘2’; the Monu-Cad version has an upside-down ‘S’, and a very strange ‘R’ with a leg that is rounded off and drags on slightly longer. This version of the font has either been corrected, or the two fonts were perhaps based on the same reference alphabet. I am unaware of any other software that contains a version of the font.
