Nice one, and you're right... unbelievable what price they bring nowadays.
Don't think this one is worth much, but had it since i was very young. Now it's missing a few parts like the cavitation plate/small metal pieces held the lower unit together, and the transom clamp used to have like a small cupped piece on the end of the screw, and doesn't work anymore. But, used to place on whatever toy boat I could find, hook up to battery, and throw the switch on the side. I think it was either on or off and couldn't vary the speed. It wouldn't go fast at all, but still I could adjust the steering and it was cool. No idea what year it was made.
