Koken barber chair

There isn't a serial number under the seat as suggested. I have looked all over for it.

The hydraulics still work.. It  has the seal skin strap for sharpening the straight edge razor. I have a childs seat, I don't think it is orginial to the chair. The leather is what you would expect. The chrome needs to be redone. The porcelain is in great shape.

I am not sure of the age, nor the current value.
