According to the seller (who picked it up five years ago), he was told it was from the 1960s, but it could be a little later. Certainly hay 'era' anyway. It is said to be heavy, possibly made of laminated wood, with some chips and marks picked up over the years. See the listing for a close up shot of that.
If you are going for that late '60s or 1970s look, it's certainly worth checking out. At £150, it doesn't seem an extortionate price either (as long as you can get it in the house).
