Heller's 1/400 U-boat kit is nowhere near as good as the more recent Mirage releases (particularly annoying are the drain holes represented as raised blobs of plastic) but as I got it in the Airfix "Kriegsmarine" box set I thought I may as well build it! It is painted as U-82 which I was building in 1/150 at the same time (this will be in the gallery soon, hopefully) The rails are made from modified and reshaped bits of 1/350 photo-etch railing.
