I agree, sounds like the paravanes to me.
One thing I HAVE noticed about a lot of kits these days (coming back from a 30+ year break from the hobby) is that companies frequently come out with "generic" sprues of parts, which may be used in several different kits. That drove me nuts with my first 1/700 plastic ship kit, a Skywave/PitRoad Oliver Hazard Perry class frigate. I was used to the old days, where every part in the kit went on that model, and nearly drove myself to distraction trying to figure out where some of the little bits went.
