Sometimes, when folks are cleaning out the elders house after they pass, they have no idea of the value of certain items, and they just haul it all down to Goodwill to get it out of their way.
I imagine so. Though these ones don't appear to be THAT old - and there are three of them.
One can imagine the unfortunate thought process that people might go through if we carry on with that scenario. Sorting through their deceased's camera gear; "film camera - GoodWill .... film camera - Goodwill .... film camera - Goodwill ... Ooooh (10 MP) digital point&shoot. That's a keeper!"
