IBM Selectric Composer used to try and reproduce a memo

[MODU]

The "1"s in the memo were really "l"s. Whoever made this attempt wasn't doing a very good job.

What happened to the argument that typewriters don't have closed "4"s?

Those are definitely "1's."  Look at the top of the character.  You will see that there is only hash to the left of the top of the character, completing the "1."  You can see the "I" shape in the second part of the example in the word "Interceptor."

Nice try though.

I just found out what jfern did.  He saw the images I used, and assumed I was pulling them from freerupblic (a known highly partisan site.)  Thus he figured the arguement about the "1"s being "l"s was part of it.  Knowing this is a weak argument he set it up and knocked it down.  A total strawman argument and not a part of the case beign asserted here.

In the original document "l"s were used instead of "1"s. Look at it closely.

Again, go back to my post regarding the line where it says "Interceptor."  You have the capital "I" on the same line as the "1."  It is clearly different characters.
