Hiram Hibbard pardon

[Steve]

I just came across this story from 5 years ago about a forged Lincoln pardon:

Here's a link to a transcription of the forgery which actually made it into the Collected Works:

Does anybody know of any updates to this story? Since Hibbard is actually known to have been pardoned for desertion, has anybody been able to find a copy of the real pardon yet?
