Thank you for viewing! This is Sparco. Bottom mount type. The issue is that the reclining adjustment knob is missing. ※ It still works, even without it... It has a leather-like appearance, and I liked it, but I'm selling it now. I don't know how to ship it, so I'll only do a direct hand-off!! Pick-up days are basically Saturdays, Sundays, or holidays only. Thank you.
