From the 1960's this is a Ludwig Throne! Height adjusts by knob/pinhole system which works fine.This has been rigged/repaired but does still have some issues. Shows signs of use and age with scratches, rust, and pitting in the chrome. Where legs connect to main tubing it is cracked. A screw has been rigged through it so it is still holds. Legs have a noticeable wobble. Seat is nice and cushy! It's in good shape with minor scuffs and scratches. No rips. See the pictures for more details!
