Ots help needed

My mate is building a replica of hms hood battleship,he has about 90 copys but has lost issue 18,anyone know any specialist magazine sellers online,thanks in advance guys

Its not one of them magazine type ones where you get a different piece each week is it? First weeks issue is like £1.99 but every issue after that is something like £10pound and takes you 10years to complete lol probably been cheaper for him to buy a real battle ship. Just tell him to phone up the company who issues the magazines. I'm sure they will have a spare one.
