You may not even need the typewriter. For a few bucks you can buy a font from this site called P22 Typewriter.
This font is based on the typeface of an old typewriter and it is strikingly similar to the text on the Bomford document. Right down to the out of place #1 where it shows 10th April, 1959.
All of the other ‘1’s in that document are lower case Ls instead of the #1. There is a picture of it on this thread: http://www.freerepublic.com/focus/news/2306351/posts?page=6783#6783
Yes, and note that the typewriter in the photo I posted lacks a numeral 1 key. A lot of typists back in the day were used to having to type lower-case l for the digit and continued to do it even when using a typewriter equipped with a proper #1 key.
