Chair has a history: It was originally my bosses chair, she got it from her father who ran a lumber supply store Piercey's and later became a big-time developer.
Leather upholstery stuffed with horsehair, still has the original casters and they even roll (how many plastic shite chairs can claim that?).
I reckon it might be 1920s-30s vintage judging by the style.
Thanks Xen. That looks more or less identical to what I remember 10(?) years ago, except the keyboard is smaller and potentially looks less full of ash? But surely not!
