I had found in SP the apparent testament dative and inventory of Adame Keir in Hugstoun (Huxton), from 1655.. After much thought, I bought it. And from the first words it's quite apparent that is not a testament dative after all. (I'd thought that it seemed a bit long for a TD, at 5 pages.)
It's a testament testamentar - in five pages of closely-written secretary hand, with the writing on the page behind bleeding through. The first part seems to be inventory but near the end is the actual testament, from which I'm hoping to get some knowledge of this person about whom I have almost nothing else - only a line of his son Adam's apprenticeship record in Edinburgh.
About two years ago I had my eye a bit in for this (thanks to the various bit of excellent help that are scattered around online) - I will have to recover that skill and may well be sending bits of it to here from time to time. And if anybody would like a real challenge and wants a bit of secretary hand to practice on ... let me know...!
So here goes... but oh, I'm quite delighted to find it!

What a great find! You're very lucky, even if it takes a year or more to decipher it 
I'm in the middle of some faded ink with bleed-through from the other side 17th century French documents from Québec, so I fully sympathize!
