Silver Suntour seat post clamp. This is the 1 inch type and fits all the old school BMX frames, not the newer, larger frames.
No marks and not even sure if I even used this one. Also not sure, however, I think it might have originally been gold and the anodising was chemically stripped, just like we all did back in the day when we wanted a colour change and couldn’t afford to buy new parts!
Original equipment on some old school BMX bikes such as Redline.
