What textual details show that Winston is curious about the past and may even yearn for it?

Winston loves any time before the Party controlled everything. He wanders into the prole section and buys things like a diary and ink pen. He knows these things could get him in a lot of trouble, even vaporized, but he still covets them. Winston returns to Mr. Charington's junk shop and sees a glass paperweight with a pink shell in it. He loves it because it existed before the party and the party had not been able to change it.
