Does anyone know what year in the 60`s the Ralph Kester Ching Ring was first introduced? Also were there MIJ knock offs of it produced in the 60`s? I have one but can`t find it yet and seems to me it wasn`t the real Kester deal and i got it in the mid-late 60`s.So i`m thinking it may be MIJ?Any ideas on this guys,thanks.
