That's a bridle leather Prix de Nations, between 20 - 30 years old.
They are wonderful saddles, lots of folks are very fond of them. Check eBay for a value.
And no, it doesn't make any sense to try to add knee rolls to an existing saddle. A saddle with knee rolls has a different size and shape flap than one without.
I would LOVE to find that saddle in a wide tree. Maybe you should sell it and get an something with knee rolls if that's what you really want.
