Still "mothballed" from all my multiple relocations are my Boxer and Hiryu carrier builds. And behind them I'll bet another ship or two, whose identities slip my mind, at the moment.
Regarding planes I do have mothballed my Italeri 1/72 Do217-k2 build - all but finished, except for (the mass-production of) its Fritz-X guided bombs. Even closer to completion is the refit of my Revell 1/72 RAAF Boston-II, which I really should unpack and knock off, in short order. My Italeri 1/72 Hudson MkII for some reason sits with its customized fuselage windows complete - maybe because that was the most interesting part of the build, which then lost steam. But this one, too, could be finished very quickly now.
Likewise, my Monogram 1/48 bubble-canopy SkyRaider has its wing-fold mechanisms completed, as does my Accurate Miniatures 48-scale TBF Avenger - both true, realistically-folding mechanisms, the latter far superior to the one Revell once released. Improvements learned from these are prompting me to completely re-do the wing-folding on both my Hawk 1/48 Banshee, and Revell 1/48 Cougar as well.
Then, there is my Lindberg 1/48 F-11F Tiger, Revell 1/72 IL-4T torpedo bomber and Lancaster B-III Tirpitz-raider, on all of which I guess I have tecnically made starts by doing some cutting, gathering/preparation of replacement parts - and a whole lot of planning.
The same could no doubt be said of five or six other ships - particularly CAs, CLs, DDs and DEs - some of whose exact identities have not yet been decided.
In other words, I have about 10 years' worth of unfinished projects lying around!
