Yet another donation from Bill, this is another almost complete set but is missing the Mechanical Excavator trailer. In one of the pics you can see a duplicate Radar Dish trailer, I got this along with three broken explorers in a very poor state and a Polar Command trailer off ebay last week for the grand total of £1 lol. It may be possible to turn this into a Ocean Explorer trailer with the addition of some well chosen green paint giving me a full Ocean set.
