£65 posted, worst mark is shown next to my finger. This is a Pure Energy tank worth £220 on Rap4.co.uk, the bottle is in great shape and just out of test but will pass another one easily, took it into my local dive shop and it will be £35 to get done or you can post it to somewhere like HPAC who will do it for the same price

These tanks are extremely good and proper high quality, it still has 10 years service life left
