Wright & McGill Eagle Claw Red & White Bass Zoo Ka In Box

This vintage Eagle Claw Bass-Zoo-Ka lure is very nice and looks unused. The box is marked Bass-Zoo-Koo No 301-0 and the cardboard insert is marked Bass Kil no 301. From what few Bass Kil lures I could find, they looked the same as the Bass Zoo Ka, so I'm not sure if that was interchangeable or not. Either way, it's a great combo!
