I'm sure someone actually cares, just no the "technician" who worked on
it, or his supervisor.

Yeah, someone *should* care...but I don't expect anybody does.
You could always put the lens on eBay with full disclosure at, say,
65% of expected price for a mothless one, and see if anyone bites.
You'd be surprised.
Never used the Sigma 20mm. Did own the 24mm version for a while, which
I used for concert shooting. I sold it to Igor on this list, who I
believe used it for baby shooting :-)
Looking forward to your comparison pics. I think you should call your
e-mails on this subject "The Mothlens Prophecies".
Cheers,

So I opened the FA135 up last night. On the outside it looked like Pentax
service had never even gone inside. On the inside - sure they had been there.
I bought the lens new from the local dealer around 2002, it was the last one in
stock here but it was still new and from the dealer.
Somebody had tried to force the back element open with the wrong instrument,
markings on the barrel would suggest they failed. Also the moth stuff inside.
Removed the aperture thingies only to find one of the biggest screws in there
was badly damaged by somebody with background in changing wheels, not servicing
fine instruments. Jackass, Philips power drivers should never ever be used on
JIS screws. Aperture spring being glued in place and not swapped out for a new
one is a minor nitpick in comparison.
Didn't want to take it apart completely - helicoids and all - so I tried to
unscrew the rear element with a properly softened large area of contact tool
(just dumb oversized pliers with rubber pads) and it worked. So I removed the
empty pupal case (no sight of moth itself) and all the debris.
Here's a picture for those of you who got this far:

Properly cleaning the lens would require total disassembly and even then I
don't know if it would be any good. Those monsters weave their cocoons and
strands of that weave are between elements even further inside the lens. Even
if I could open it up that far I don't know if I could completely remove
everything.
So that's it probably for this lens. I will test it against my other sample but
there is no real reason for me to use it anyway when I have the other one. I
don't see a good way to clean it so well that there is no sign of the moth ever
being there so it can't be sold either. I might go through the adventure of
disassembling it completely, cleaning it and putting it all together but I
don't see that happening before the kids grow up :)
Pentax should probably know about the sad state of service in Europe but I
don't see a way to get this information to anybody who cares. If service at
Pentax authorized service centers takes half a year and is performed by idiots
who only make things worse, somebody should care, no? Oh well, I feel better
already.

Don't lose heart, they might want to cut it out, and they'll want to avoid a
