The Octonauts childrens magazine issue 46 is offering a bright orange shark-mouth submarine which could easily be re-used as a VSF/Steampunk sub (it even has rivets!
It could just as easily be a one man space craft!
check out WH Smiths for Octonauts Magazine issue 46 20 May - 16 June 2015.
The submarine is styled after this model but is much smaller - being 95mm long x 76mm wide (across wings).
