Have posted it where I can. A good place to post is
The NFED. Equestrian Information for the Central South. Horses, Ponies & Equestrian Equipment for Sale. its a new forest website run by friends of mine, i know its a long way down here but the foal could be anywhere by now and we live in a hugely horse populated area with many gypsys driving through that often buy/sell horses. Theres a huge amount oif horsey people there including farriers and vets.
If you message Steve who runs it he will post a stolen ad for you.
