I believe @Bogie also knows a thing or two about them as well.
Sorry to hear about your saddle. That really stinks. Are all horses and people okay?
Ainsleys are great saddles. They are not “in-vogue”, so do not command high resale value… but in my experience, they retain shape and condition incredibly well. The leather quality is great - soft and buttery and you can get a steal of a deal if you find one used. I have had no problems with my Ainsleys. I have an Ainsley from high school that, other than an unfortunate run-in with a mouthy TB, still looks like a million bucks. People regularly comment on it and confuse it for a french saddle - most recently someone asked if it was an Antares… IME they get beautiful patinas when well cared for. I have a second one that is an Ainsley Chester XC that is also very nice, fits a wider variety than my first Ainsley (the flap lettering on the inside is worn off, so I am not sure which Ainsley the older one is, if I had to guess it is an Ainsley Pro National).
Ainsleys, the older ones anyway, were very close contact with typical pencil-roll flaps and minor knee blocks. Despite this, they are incredibly secure - they have a flattish seat, but it is very “scoopy” when it comes to big drops and ditches I always felt 100% in the tack and with the horse. Great for galloping tracks and big fences. The XC Ainsleys have forward flaps and seem to be especially popular with tall leggy riders. I am not tall (barely scrape at 5’6") but all of my height is in my legs - I fit very well in the Ainsleys. Some people think the saddle encourages a chair seat but IMHO all XC saddles with forward flaps will put your knees in front of your point of hip, it’s just the design of the saddle.
The tree points of the Ainsley are straight rather than slanted or curved back like in newer models, so before you purchase just make sure a saddlefitter eyeballs that. I ran into some soreness with one of my TBs who just didn’t have enough shoulder clearance with the Ainsley but it was because of his own conformation, not the saddle’s.
Last summer, I “upgraded” to a Stubben Zaria because my horse needed better shoulder clearance. I miss the Ainsley everyday. The Zaria is close-contact too, but it just doesn’t have the same feel the Ainsley did.
Here are some pictures to show you how well these saddles age:

Like I said, I’ve had that saddle since HS. Love it to pieces. Just wish it fit my current project, but he’s a big, big atypical TB and that saddle is better suited for a more typical TB build.
