I hadn't noticed before, but the helicoid for the old 24mm f/2.8 (with
the silver filter ring) is the
same as your 21mm f/3.5 (Olympus part #ZJ104800). If you can find one
of these with bad glass, you might get your repair tech to use it's
helicoid to fix your 21mm....

If the internal body that holds the rear lens element has been bent,
even a new helicoid won't help, but I can't imagine how that could
happen. Maybe something has been replaced improperly....
