From the digging around I've been able to do, this is the handiwork of Russian seats and wheel-making firm
MBS. (Don't let its .de German website domain or use of "premium German Nappa leather" fool you). Although they also dabble in Nissan Patrol / Infiniti QX80 and Mercedes V-Class van and G-Class upscale 4-seat conversions, it is clear that their main product and preference is for Toyota Land Cruiser 200 and Lexus LX conversions. Here's a link for the MBS LX 570 Autobiography page:

Speaking of which, I can't get over their brazen cribbing of the Autobiography name from Range Rover. Even the Autobiography badge in the rear center console appears to be taken straight from a Range Rover. 😡
