You would think with such big haul like that there would be a few "top enders" You still might dig something out that is Mid-high range. who knows. A place to start is what do you have there that has a Reynolds 531 sticker or Campagnolo? etc.

Other than that people want vintage low-mid range model riders, but they expect them to be refurbished and don't want to pay that much. (which is tall order for with all that inventory)

Dust um off and move them "as is" IMO.
