I would contact the National Archives. You can request a copy of the original document and it's preferable if you have the citation information, which fold3 has. I have done that on several occasions.
One in particular comes to mind. I spoke to a live person there (yes, you can do that) who tried to talk me out of a copy of the original document, saying, "All the information from the original document is on the fold3 cards." I persisted and they sent a copy. There WAS additional information on the original (the names of three men captured with my ancestor) which made it possible to clear up a family mystery. It was priceless to me.
I've attached the card and the original document. The card is difficult to read but it says exactly what the original document says about my ancestor, C.P. Snell. But look at all the additional information on the original document.
Bob Velke is right, though. Chances are you won't find anything new or exciting, but ya never know.
