I may be mistaken here, but the pics above look like a larger version of a plain old freashwater spinner (mepps, roostertail, etc.). It is my understanding that a "spinner bait" has two arms in a "V". The line gets tied to the point in the "V". One arm has either single or multiple blades and the other arm has the hook and some sort of skirt. I used one that had a squid skirt last year off Monomoy with good results. Different terminology in different areas I guess.
