Having a bit of a clear out again, so this is up for grabs as I havent used it for a couple of years. I think this was 10 gallon. It does need a new tap, as it blew a small hole in the side the last time I used it (see the 3rd photo). Great for sorting out rust spots and rusty seams. Collection only, or sort your own courier as its pretty heavy (probably still got grit in it!) £50 ono
