My recollection is that Pyro did indeed make two fairly large (18" or thereabouts) fishing vessels. one was a trawler, rather similar to the Revell one we've been discussing but (I think) a little bigger. I believe it was based on (i.e., pirated from) the Model Shipways trawler Hildina.
My recollection of the other Pyro kit is extremely vague. I think it was a tuna fisherman - and, again, may have been pirated from a Model Shipways wood kit. I vaguely remember building it when I was quite young, and not liking it much. That may, though, have been due to the fact that my taste for seafood hadn't developed yet.
Both of these were 1950s kits. If memory serves (as it frequently doesn't nowadays) they weren't bad for their time, but that time was long ago. I think Lindberg may still be selling them; it seems like I've seen the trawler in a Lindberg box fairly recently. My guess is that either of them - like the Revell kit - could be turned into a decent scale model, but that it would take a good deal of work.
It's a shame that so few modern civilian ship kits are available these days. It's occurred to me more than once that the manufacturers may be missing an opportunity. Kits with movie connections have, as I understand it, done reasonably well in the past. But I suppose an Andrea Gale from "The Perfect Storm," or an Orca from "Jaws" (hey, man - dig that 1/48-scale shark!) would be too much to hope for these days.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
