This is a batter dispenser for pancakes, donuts, muffin, waffle batters etc. It has a stand and a spring loaded lever to dispense precise amounts of batter. The first 2 pictures are of my unit and the remaining pictures are promotional shots I found on the web of the exact same model (and the dimensions in the third photo are correct). 

You can collect in person from postcode SE1 (Bermondsey, London - nearest tube station Bermondsey (Jubilee Line) or South Bermondsey (1 stop from London Bridge). You can pay cash on collection (you'll need to show a barcode that ebay gives you if you do this) or in advance through ebay. Either is fine.
