Removing lens elements...

Hi, all-

I'm working on a Wollensak 159/9.5 lens right now. There's a ton of grime between the elements. On the front, I was able to remove the retaining ring, tap the housing ag'in my hand for a while, and the rear element popped out, allowing me to clean between the two. The rear is assembled identically:


However, the element that should pop free just barely moves.

How'm I to remove this rear glass? It's got to come out - there's too much scum between the elements to use the lens.

Ideas?

Thanks,
Scott

A rubber sucker, a bit like on the end of an arrow from a child's bow & arrow set, that should do the trick.

Thanks, Ian - I'll see what the kids have lying around.
