Hello Richard and welcome to the forum.
Cut down the fleet !!1 yes. unbearable. Tell me, do you have them boxed up or are they displayed on a shelf (albeit in the garage)?? I find that boxing models is the way to go as they can be stacked, if nothing else, so saving space, and do not collect dust and so on over the years.
I know what its like having long term projects hanging around, you lose the impetus to finish them, despite, as in your case, having done most of the work. I have a 1:96 scale type 42 destroyer that sat in the garage for some 20 years or so as just a hull with running gear and superstructure, and was on the verge of binning it, but made a push to finish by buying just sufficient commercial fittings to add the necessary (guns, bollards, ships boats etc) to make it look ok without going to the full monty. Glad I did as the ship looks great and I just love the look of the stretched hull later 42`s, one of the reasons I bought the fibreglass hull in the first place.
As to quiet pond in the highlands???
