Amphion Class Submarine Conversion

I found that I had a spare 1/3000th scale Navwar model of an Oberon class submarine in the bits box, so I thought I'd have a go at converting it into a modernised Amphion or 'A' Class submarine for my Indonesian Confrontation project (thanks to David for the idea). This will involve cutting down the sail and reshaping it leaving a step at the base, so nothing too complicated. I can then deploy her for clandestine landing operations, dropping off the SBS in the middle of the night to do all sorts of cloak and dagger things, as well as using her for patrols, surveillance and similar conventional roles.
