Not sure who made this one, but in nice used condition, a few bumps and bashes as you'd expect with age. Faint cracking/crazing in middle of seat where post joins seat (see pics). 

There is a seat cushion that someone has sprayed gold, not sure if this is original.

Feels really solid, and rotates smoothly. Seems to be a plastic seat with weighted fiberglass? base.

Collection only, in Cornwall.
