If you're considering buying one of the many second-hand saddles available, you should get a saddler to look it at it and check for any internal and external damage. You will also need a qualified fitter to fit the saddle, which will probably need adjusting.

 

Check areas of wear on the saddle. Girth straps and stirrup leathers are the most likely places to find it. Ask a saddler how bad they think the wear is. Scuffs, scratches and damage to the cantle and pommel may indicate that the saddle has been in a fall.
