Defunct vintage roller skates (Wallingford)

Extremely elderly roller skates, no longer functional as skates because the leather uppers are falling apart. Look at the solid undercarriage! These are the kind of skate wheels people used to repurpose to make skateboards, back before you could buy skateboards already assembled. They weigh approximately a ton. Skates were last used to skate around the Microsoft campus late in the last century or maybe very early in this century, before the leather died completely. I'm not mentioning the shoe size because (did I already say this?) these skates are not functional as skates.
