This is Pica font and the #4 is open top.

Pica and Elite (may be similar to Courier) are the two types on the machines I remember using from that time, I am sure there were others. Elite may be similar to courier, but I haven’t done a close comparison.
I didn’t find a font on my computer (quick look) that looks like what you have for Pica, it fact, of the ones I looked at, none had an open 4.
I’m pretty sure the Kenyan document is typed in Elite font. Most typewriters of that era were either Elite or Pica. I know, because I used those old machines.
Look like a good match. The lower case L was used as the numeral 1. Capital O and zero are also the same.
