Found them in a drawer...from the late '70's.  They are fished like a Silver Minnow.  And yes, that is a nylon skirt.

 

Looks like a Blade Dancer...I know it's not, but Berkley had one similar at one time

I believe that is a "Dirty Bird"    Not certain who made it, Whopper Stopper, maybe?  They pre-date the Berkley Blade dancer by at least 5 years, maybe more.  They were marketed as a pad/grass bait.  I have one - haven't used it in years, but I have one.  Mine came with a split ring at the top of the bill.   I suppose at some time that split ring got removed so that you could use a snap?  

Another situation they were used for was as a substitute for a buzz bait - or a wake bait.   They were meant to be fished on top and keep moving.

The skirt is vinyl not Nylon!
