Delaminated eyepiece lens

A while back I got a lot of B&l stereo heads and accessories, which turned out to be in awful shape--dirty, some moldy and to top it off the seller shipped them with almost no bubble wrap. So I've been sitting on a bunch of parts units. A couple days back I grabbed some eyepieces to disassemble and clean, and found this lens in one of them.
It's completely delaminated, with whatever they used to cement the elements together having recrystallized. It's kind of pretty in reflected light, and even nicer under crossed polars (click for larger size):
At least I got something from that lot!
