Need Antares Saddle advice

I would be forever grateful if anyone could help me out here. I have an Antares cadence dressage saddle that fits my horse like a glove (my vet even made a comment that she’s never seen such a perfectly fitted saddle). I’d like to purchase a jumping saddle that fits him just as nicely but I’d like to avoid purchasing something brand new. Ideally I am looking to do a 5 day trial on something listed online and have my fitter/vet come check out whatever I get on trial. The problem is that I can’t decipher the Antares codes to even know where to begin or what saddle specs to look for. Is there a way to use the codes on his dressage saddle to find a starting place for selecting a jumping saddle? For reference, the saddle says:
Antares Cadence
22 2445
2N/2+0
17,5 26

For the dressage saddles, there’s another set of codes printed on the very edge of the underside of the left flap that has the actual horse specs.

That being said, it will be tricky to compare it 1:1 with a jump saddle since the trees on the dressage saddles are different

Thank you! Very helpful!! I appreciate it.
