File format recognition hard mode

In a old old inherited MS SQL Server database, in a column named 'Image' of type TEXT we've discovered an encoded image (we assume). And even if its not critical to the work we are doing, its damnably intriguing. Can you help me crack its provenance ?

The blob is around 2000 sets of 8 hexadecimal numbers, not the base64 encoding I'd use or expect.
We've found a similar pattern in a .draw (?) file discovered online http://www.vorlesungen.uni-osnabrueck.de/informatik/pt/code/Html/Sommeruni/drawings/7.draw
so the encoding is not unique at least.
If this a Windows-thing that would be comforting to know. Or any tips that can be offered to get to the bottom of our mystery.
