Affordable 90mm?

It's not age that matters, but how the old ones have been stored. Angulons should always lie flat, especially in hot climates. The inner elements in each cell are only held by the cement, and old Canada Balsam tends to "creep" if the lens is stored "vertically". My own 1939-model is just as sharp as my 1959-model.

Does it matter which side is up when you store it?

No, as long as it isn't an edge.

Thanks... My new-to-me one is very sharp, and I want to keep it that way!
