Soaking the pen in warm water for an hour or so works well helping to loosen the section on the later pens but of course be very careful if trying the same technique on pre-war casein pens.
Nearly all postwar Conways are casein, too!
I would strongly recommend against soaking ANY Conway Stewart for section removal, and I practice what I preach. With the exception of eyedropper sections which can get gunked up by dried ink, I use only heat (variable temp heat gun) for section removal (other exception: metal-to-metal joints prone to corrosion).
When I was starting out I used to soak sections to get them out, too. I had a much higher breakage rate back then, and ruining more than a few pens through staining.
