Braves Beistellpferd

For personal reasons, I am selling my 16-year-old Mecklenburg Warmblood gelding.  
He is barefoot and well-behaved for the farrier, as well as compatible with both geldings and mares.  
Currently, he is in a herd of 6 geldings but is also familiar with mixed herds.  
He feels comfortable in an open stable and tolerates grass very well; he does not require special feed.  
He enjoys playing with others and does not have a dominant rank (so far, neither low-ranking nor high-ranking).  
Due to various findings, he cannot withstand permanent exertion (riding, lunging). More details available upon request.  
He is currently sound but can only be moved at a walk (possibly also at a trot after some conditioning work in the terrain).  
He is familiar with groundwork, is sensitive to aids, and is clear-headed.  
I would be happy to provide more information upon request.
