Wow, I think somebody got scammed. Those are furniture tacks being used
to hold on the naugahyde, and the tip is definately from a hose
fitting: see http://tinyurl.com/dh73r.

The bellows is similar to this one
http://www.chipcarving.com/bellows.htm but not as well made. I don't
think there's any way that the original is an antique.
