The Helicopter Carier is HMAS Canberra (by Albatros), Blue Marlin is by Rhenania Junior and That leaves the USS Cole and its underwater hull. I have a set of the Cole salvage, built up by the late Calvin Simms, comprising a red hull Blue Marlin and an Argos USS Cole with a Rhenania Junior underwater hull added. Calvin told me this had been a commission from someone who had insisted in a red hull on Blue Marlin but the Argos USS Cole was (and mine still is) a bad fit on the Rhenania Junior UWH. Since all the models are metal in Calvin's set, I am not surprised because because it is very difficult to predict the shrinkage of the hard moulds when they are made by the same modeller, let alone if the models are made by different makers using different mould-making mixtures. Therefore, I would suggest that the USS Cole might be a Hobbyboss version.
