Yellowhammer - the campaign is over Aug. 31, 2020 - so if I were you I'd pick something easier to complete in the time so as not to feel rushed.
What do you have in your stash that you're considering?
These were the kits on top of the stash that I'm considering right now:
Mirage kit 40028 of WWI torpedo boat V106. 1/400 Disp. 360 tons
Mirage kit (??, no box) of Type IIA U-2. 1/400 Max Disp 381 tons
Zvezda kit 9033 of Medieval Life Boat. 1/72 Disp unkown; Capacity about 12
Lindberg kit 72120 of Tow Boat River Queen. 1/220 Disp unknown; assume 150-200 tons
All are fairly low parts count so should be doable in the time remaining. I'm leaning toward the lifeboat as I have some seated 1/72 scale civil war figures I could use to provide a crew for a patrol/sentry boat.
Do you have any recommendations?
