Info from vet who scanned it
Country: NLD

Figuring that the horse was Dutch (tho not necessarily KWPN) based on the country info, I looked around in the http://www.horsetelex.com site and determined that what we have does not appear to be a KWPN number. Those start with the last two digits of the year of birth, followed by five additional digits. I tried plugging in various parts of the above # to no avail.
The horse was probably born late 90’s and is grey. He does not appear to have a brand, but is not clipped so it’s hard to tell. I think that the Dutch stopped branding at some point before the U year.
He may (or may not) be a Zangersheide. I think I heard something about that at one point.
