You can get $50-100 for the fan and motor, ebay is the place. There were different versions of that motor, front and rear intake, the rear is worth a little more. Neither the fan or motor have any collector value, they are only valuable to someone who wants to USE them. Like you. Consider that the only other engine for this plane would be an OS46, and they easily cost over $100, and don't put out significantly more power(if at all), why not use what you have?
