I came across several old Pentax lenses which have probably been in storage for at least 20 years.
Nothing fancy. There's an 85 mm, a 35 mm, and a standard 50 mm.
They aren't beat up, but when I hold them up and look through them, there appears to be fine bits of dust on inside surfaces, and other very fine "stuff" that almost looks like mini-spider webs.
Sounds like fungus (the spider web stuff) so the value of getting them properly cleaned and serviced depends on exactly what model they are. What does the writing around the lens at the front say?

Is there any way to do interior cleaning of such lenses or should I just dump them?
If it's pretty hopeless, I'll offer them to someone who might want to experiment...
