Looking for the font on the keycaps on this keyboard (Honeywell Micro Switch 1970s and beyond) or help recreating it

[glue_eating_keyboard_kid]

Used by the Honeywell Micro Switch division on their keyboards from ~1970 onwards

I'm not very hopeful that an exact match is out there so I would also appreciate any advice on recreating it; the free software I tried was really horrible

Thanks in advance
