Hi Gang,
I have a Heliar 21cm, that has slight separation around the edges that doesn't affect the image (in so far as I can see).
I am interested in having the element re-cemented by someone reputable who specializes in this sort of repair. I'm in the US/East Coast, however as the lens is some what of a rarity, I don't mind shipping out.
Just want to take care of the lens for the next generation, if possible
