Daring declaration: Historians identify rare copy of Declaration of Independence in British archive
After discovering a highly rare copy of the Declaration of Independence in a small records office in the south of England, researchers were able to date the document to the 1780s, and say it sheds light on the tumultuous politics of the era just after the Revolutionary War. Ref. Source 5q.
Yes this would be very interesting to find out more about this. I figured they had two copies made. One that the original signers would keep for themselves and one that they would have sent to England with their declaration. The fact that each was signed in a different order makes a lot of sense.
