I have noticed the exact same thing about my GulfStream models. Very strong smell even a couple of decades after the casting. I’m not sure why this is so; possibly incomplete curing of the two components? And yes, it does smell like the temporary resin odor from sanding old BWN YKM kits. And resins from Blue Ridge models have no smell.
I doubt that there is significant general toxicity to the smell. Your olfactory system is one of the most sensitive senses and can detect parts per billion in the air. The main toxicity is irritation of the nose and skin on exposure. In extreme cases, it can lead to respiratory problems on prolonged exposure. So some individuals may be much more sensitive to the smell and resin dust. When sanding resin kits, I always wet sand to keep the dust down.
Best advice may be that of a late 20th century president: Don’t inhale!

Good Morning!!
Noticed recently that my 1/350 Gulfstream USS Ward (completed over 20years ago) still gives off that particular strong resin smell that I’ve noticed from old Gulfstream and Iron Shipwright models.
Probably being paranoid here but couldn’t help but wonder if there’s an ‘off-gassing’ component to any of this.. and of course any potential toxicity from these old cured resins??
(Old BWN/YKM kits only give off a strong smell when sanding the cured resin etc.) Zero odors from old WEM or Atlantic models kits.
Not planning on trashing my resin kits anytime soon but more knowledge is generally a good idea.
John
