Just had a look at my Catalina.
1994 boxing (per ScaleMates) of the 1964 Airfix mould, manufactured by Heller in France, under the Humbrol umbrella.
Bucket loads of flash & warped ... Oh,
man, is it warped!
Still, it's the most likely candidate for this build, followed by my (original 1978 boxing) Hasegawa 1/72 Viking S-3A (the Italeri 1/48 S-A/B is going to require more time & effort than I can spare).
