The picture here is of the Lindberg Bobtail Cruiser, assembled, and the beginning of the drydock. The scale of the kit, approx. 1/170, is close enough that I am using N scale, 1/160, figures and building kits for the shipyard scene.
Here, the 1' X 2' drydock module is incorporated into the 2' X 4' diorama.
and here, a close-up of the ship in drydock. the caison/gate for the dock hasn't been built yet. The "white" hull in the background, is the Revel "Russian Spy Trawler Volga" kit, and is on the building ways.
The decision to upgrade the model wasn't easy, as there is very little aftermarket parts, so all the changes will have to be scratchbuilt. For example, in the last photo, notice the "blank wall" forward bulkhead of the pilot house, there's supposed to be three portlights there, same size as the rest on that level, and all of them need frames around them.
