I have a pre-World War II 210mm Schneider lens that has some "stuff" between the elements and was wondering if anyone could recommend a good service company in the USA that can disassemble and clean it up.
Thanks for the info and link. The reason I used "stuff" is because I'm uncertain as to what it is. There doesn't seem to be hyphae, so I am hoping it's not fungal contamination but only dust.
