This has just been taken off my bike, a 51 plate. It's the larger (20 litre) capacity tank for the square headlight Mark 1 600.
There's a shallow dent where the previous owner's knee hit it in an off, hence I've finally replaced it with the one he gave me when I bought the bike from him 11 years ago! It might be fixable if you've got the know-how and the tools. Apart from that and some small wear and tear chips it's in great condition as it's had a tank protector on it since I got the bike.
The ones on eBay at the moment are going for £125 to £175 but don't have dents so I think £70 ono is reasonable.
Postage options: Parcelforce express48 - £16 (2 day delivery by c.o.p.), Parcelforce express24 - £20 (1 day delivery by c.o.p.) or pick up from Milton near Cambridge.
Edit: added photos. You can see the dent in the first one. The white marks on top in the second one are actually the reflection of the can on my bike. You can see the yellow of the number plate as well.
