About 30 years ago, my wife bought a "Dynamo & Solar radio" for "about ten bucks" ($10 US) from the catalog of the company now known as "RealGoods".
RealGoods is primarily a solar energy company and installs roof panels, but they also had a catalog of solar-related stuff like clothes-lines, inverters, geo-thermal pumps, and this radio. Later they has a web-store. (Their online store is currently off-line for renovation?)
Holding it, it is clearly a standard AM/FM "transistor radio" built longer to hold a crank, gears, and motor (generator), with a solar-cell on top.
It has stood on the window sill for years. I do not remember putting batteries in it, although the batteries in it are a brand/model from the last 10 years.
2 years ago we packed the house and moved to the coast of Maine. While most of our stuff was still in (dark) boxes, the power went out and didn't come right back on. We dug this radio out of the box to find out if Something Happened. (We lived through the Great Blackouts of 1965, 1977, and 2003, also the events of 9/11, so we like to know why the power is off.) It played poorly. Turned the crank for a minute and it got better, left it in the sun and it played well. All the radio stations were on the air and playing their usual bland music. Never did find out why the power was out.
The house we moved to "needs work", more than I can handle, so we have contractors here many days. When Dana is here we put the radio out so he can sing along with the oldies while hammering and painting.
We don't see it as "collectable", it is just 'the radio". Its relative age and unique power do make it noteworthy. I've uploaded a photo and am adding these personal comments.
