Original NOVA wiring gutter&vacuum parts or not?
 

I'm in the process of sorting through my collection of parts and attempting to identify some pieces that I'd forgotten about. If anyone can help me identify the application of these pieces and possibly a fair market price on anything that might be desirable I'd really appreciate the info. Thanks in advance.Couldn't get the pics to load through the site so I added a link.
