Mystery trotting horse long code

I don't know if anyone can interpret the code in the photograph better than I can from the base in real life - sharpened up by Photoshop it looks as if it might be MF17 325 or similar..

It is a smallish horse - pony size maybe - and thoughts were either a Cossack horse or possibly an Ancients one?
