Schon cue ID Please.....

[OTB]

I just took this in and can not find the model anywhere, The cue has a leather wrap with 2 shafts with ivory ferrules & one ferrule has a small crack on both sides....6 Palm wood points....12 Ivory Diamonds. It was made before they put schon on the shafts if that helps so pre-1993...New info:..The original owner purchased it in 1989-90 he says....having this info now , means it would be a late Runde era cue........thanks for looking......OTB

Shafts:
1.) 13mm ( has 2 small cracks in ferrule )
2.) 13.25mm

Cue is For-Sale or Trade....
