I would think that "light cleaning" is in the eye of the beholder. I've seen "light cleaning" that looked like someone took a rotary sanding disk to the barrel. On another occasion, "light cleaning" meant that it sat in the back of a closet for 50+ years and the owner wiped it down by pulling it through the hanging clothes before handing it to me.
Pics are a must. Can't point out a price, haven't seen one for sale in quite some time. Note: I've also never seen one that did not have broken parts.
