While trying to figure out how the powder magazine looks like from the inside (Indy has an interesting floor-and-a-half hold configuration, different from ships of the line and most of the frigates both, with the closest, not exactly similar, but fairly close, being the way Trincomalee was built, but it's still hardly decipherable, despite all the photos I have seen), I
loosely placed the head details from Endymion (those required a certain amount of scaling, stretching and repositioning) and stern gallery from the previous model. There is still much work there to be done, tweaking and connecting the parts, but the general arrangement is there. And you can appreciate the elegant tumblehome of the hull.
Finally, there is a new figurehead.
I didn't find a complete Greek warrior in armor, but I think this bust of Alexander may fit just as well.
For clarification - I did download and took a very close look at the hold of HMS Unicorn model, but the magazine there is completely enclosed, with the light room lost somewhere inside, so I that does not answer my question. If anybody has more detailed drawings of the hold of both Trinco or Unicorn, they would be greatly appreciated.
