old camera accessories 2 - lenses (Spring Hill, Somerville)

This stuff has been in my basement for over 15 years. I don't know exactly what it is.
These seem to be two different sets of lenses.
One was in its original, but deteriorated, cardboard box. I've shown all the pieces.
The other is in its original leather? case ans still wrapped in plastic so I did not open it up.
Take one or both.
