The
Calypso is definitely a very good kit and if you can find it
at a reasonable price is well worth buying. Revell also issued a PBY
Catalina flying boat as Cousteau's aircraft, complete with figures and
motorboats, though this is 1/72 scale (the ship is 1/125)
I originally wanted to buy this kit to convert (or "de-convert"?) it
back to its original WW2 minesweeper configuration. However after
seeing the high prices it routinely goes for, I've given up - I'm
hoping either Revell will re-issue it, or maybe I'll find a cheap
built, broken example on eBay to restore (this is how I got the Glencoe
WW1 subchaser, Revell USCG Burton Island, and Lindberg Landing Ship
Dock, amongst others)
If Revell reissued this kit at a reasonable price (around £15/$25 seems
about right based on the prices of their other ship kits), I'd probably
buy 2 - one to build as the Calypso and another to convert to the
original minesweeper.
It's surprising the prices this kit fetches on eBay and elsewhere (even
recent 1990s Revell AG issues, which indicates that the demand is from
builders as well as kit collectors), but there's a depressingly long
list of ship kits which are highly sought-after due to being the only
representation of their subject and being out of production for many
years. Mostly larger-scale kits, but there are quite a few smaller ones
(Hasegawa 1/450 HMS Vanguard, Otaki 1/400 Nagato, Airfix 1/600 HMS
Victorious, etc.)
This is one of the reasons I'm increasingly drawn to scratchbuilding!
