Treadway purpleheart andMcdermott defy shaft 12.5mm

[jmf041]

I have a McDermott carbon fiber defy shaft.
It is for a 3/8x10 does NOT fit modified pin.
Shaft is straight and I picked up second hand but original owner hardly used it and I haven't used it.
Diameter is 12.5mm, unsure of tip.
$200 plus shipping and fees.
