Windsor Castle Floor plans?

[Nellybarnes]

Good evening all, I recently discovered a set of Windsor Castle floor plans and was hoping someone on here could tell me a bit more about them also any potential value? I've attached a couple of pictures to help identify the ones I have. Any information would be much appreciated, Regards Neil.

You could write to the Palace or to a Minister of public Works Dept or to the Royal Collections office. I do not know the relevant names of these offices perhaps a phone book would help you.
However, if you were to write to them including your photographs I am sure they would pass them on to whichever relevant authority to look at.
A Royal Collections officer at Buckingham Palace for instance would definitely reply to your enquiry. And probably quicker than the Works Dept.
Your documents dated 1808 look very interesting indeed.
Good Luck and remember be patient waiting for any replies.
