Is there any value to these old parts other than scrap value ???

The one thing I'll state is don't scrap any of it. It's better to give it away than lose a part that will never be made again and could potentially be used by someone.

Trying to find someone to purchse the whole lot is a lot tougher to find than individual buyers that can actually use a specific part. If you take the time to take pics of each part, along with any relevant casting numbers and identifiers, and make a complete list of what is there, you might find one buyer to take it all. If nothing else, I'm sure you'll find buyers for individual parts but it will take a lot longer to liquidate. Just don't expect top tier $$$ from either, be willing to move the parts along, and you should unload them.
