Some things I noticed when looking at the orginal scanned image: (http://cdn.thenextweb.com/wp-content/blogs.dir/1/files/2012/11/large-pigeon-message.png http://cdn.thenextweb.com/wp-content/blogs.dir/1/files/2012/...) The NURP text part contains numbers - why is number 76 on bottom one aligned under the 194 as if this is a sum (or subtraction)? suggesting the person who wrote this knew that this was important. Why is The Time of origin box underlined? is this to show that this number (1522) is to be used? Also note the style of the number 2 varies as if done by different people. Back to the code itself, a comment has been made that there are 27 blocks with what looks like a time at the end. Was this inserted here as a kind of checksum to stop any additions to the coded message? As a side note, if you subtract the NURP numbers: 40-37 = 3 and 194-76 = 118, grouped together (using the 2 in the Number of copies sent box): 31 18, swap to make the date 1831, and use the 6 as day in a month.... I'll let you google that!
