Animalbimes Cush Stitched seat

Just found this well used Animal seat in my lock up. This was one of my favourite seats back in the day, I had it in black too but unfortunately that went with a bike.

I seem to remember these being quite rare, and seeing one sell for a fair bit of money on eBay. I’m not really bothered either way as I’ll be holding onto this one for sentimental reasons (too many seats I regret getting rid of, I WILL find another Subrosa Slayer seat one day), but is this correct? Are these seats hard to come by, or have I misremembered that?
