The masts (which were later replaced with taller versions) and the guns, which are tapered sections of plastic rod superglued into small pilot holes.
Additional modelling work included building a compass house (which is fitted below the main hull and does not show up in these photos) and some minor detailing - for example, a name plate to the side of the wheelhouse, and the portholes drilled out with a small handheld drill.
The construction is now complete and took about three to four hours over a two-day period, working in the shed with simple tools and while listening to the radio.
