Familiar w/ Ainsley saddles??

I've been on a bit of a saddle search lately and my instructor has been helping out by asking other students/people she knows about saddles they have for sale. She found three (all sitting pretty on the back of my couch at the moment... much to my dad's dismay ). Out of the three, one is perhaps the comfiest I've been in... a dressage saddle by Ainsley. The name sounds vaguely familiar, but I haven't been able to find out much about it. I think it's a saddle brand in the UK?

If anyone knows a few things about these saddles or can find a website with info about them, it would be much appreciated! For one thing, I'd like to know a bit more about what its tree is made of and what type of flocking it has.

I've also got a bit of a side question that doesn't have to do with the brand. I've kind of fallen in love with this saddle, but being 5'3" I fear that the flaps may be a bit long for me. Is there any guideline for where the flaps should end on a rider's leg with a dressage saddle? Is it at all possible to have them modified?
