old headlights worth testing?
 

I did not see a "What's it worth" section of the forum. Sorry if I put this in the wrong place.

I'm cleaning out a friends garage and found these used headlights (Guides plus aftermarket, not shown). Are they worth testing? He had a Buick GN and a mid 80s ElC with a Choo Choo nose. The round T-3 is from a 68 ELC I think.

He also had a stack of older Chiltons and other manuals. Are they worth listing separately here? Or do I just take the stack to a local flea market? some are in rough shape. thx
