I only remember the "Coastal Series" faintly. The only other kit in it that I can recall is the tugboat (though it seems likely there was at least one more). The tug originally appeared in the early fifties under the name Long Beach, and was in fact a scale reproduction of a San Francisco-based tug of that name. It's been reissued several times (I've misplace my copy of Dr. Graham's history of Revell, so can't check the dates; my fault). I have in front of me the latest incarnation from Revell Germany. It's labeled simply "Harbour Tug Boat," and the scale is given as 1/108 (which is, in fact, pretty close to reality - for once). It's the same kit except for the decals and the color of the plastic (bright red instead of the original light grey).
This kit is an old favorite of mine. It represented the state of the art when it was originally released, and still holds up quite well by modern standards. (The three beautiful crew figures in it found their way into my models of the Bounty and Hancock.)
Newcomers unfamiliar with it do need to pay attention to a couple of odd points, though. In one of its earlier American issues the kit was motorized, and the entire superstructure was made removable to give access to the motor and batteries. On each of the superstructure sides (parts 45 and 46), down next to the deck, are a pair of crude-looking plastic projections about 1/8" apart. When the superstructure is assembled to the hull, the gaps between them line up with a pair of round "dimples" in the main deck. Those dimples originally were the holes for a pair of metal screws that, by means of the projections, held the superstructure to the deck. Slice off the projections, fill in the dimples, remove fifty years' worth of flash, and you'll have the basis for a fine scale model of a typical late-forties/early fifties American west coast diesel tug. I have my doubts about whether any European tug ever looked much like that (though heaven knows I'm no expert on European tugs), but in terms of representing its originally-intended subject it's a real gem.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
