Switzerland Stamp Album (remnant as found at estate sale) about 500 stamps

Description

this is from an estate sale. I know nothing about it. it's entirely possible that stamps were removed pior to my getting it (in fact there are empty sleeves). I am however selling it just as I found it. there is a sticker on cover that someone put there saying something about well over 1,500 (???)
the album is from 1958 but there are pages that date into the circa 1960s. a bunch of loose pages are in back and were either separated or not placed into rings.
some stamps are in glassines and not mounted, others (most) are mounted.
many pages are empty, there are lots of missing stamps.
I did not count the
stamps
but I imagine there are at least 500 stamps here
