Hi I'm the one who used to keep my horse at Brenfield - don't know how many horses will be going out on loan this winter, most of them usually go to colleges (eg Bishop Burton) - they tend not to keep many horses at Brenfield over winter, as the business revolves around the tourist season.
They use 'trail' saddles - they are synthetic, western style saddles, which work very well for the trail rides etc. Rare to see a horse out of work with a sore back, they take good care of the horses. The trail saddles don't go with the loan horses - there's an assumption (I think) that English style saddles are preferred by loaners. Certainly the colleges won't accept trail saddles. Guess you were unlucky to be given a saddle that didn't fit - very unlikely Shian was ridden in it at Brenfield.
