Good Find!
The sales brochure for the one-owner used Gulfstream shows interior details which confirm it is exactly the same kind of jet that Stallone is sitting in in the photo.
The 'JS' initials on the leather headrest in the brochure's jet is likely a custom embroidered initial of the previous owner. I suspect that if Stallone owns the jet he's in, his initials would be represented.
The Laurel has a JS in the middle.
