I have an Ebony JT-1 with 2 30" shafts (12 mm and 13 mm), Efren Reyes taper. The cue is straight together and apart and in good condition. There are only some chips in the finish of the butt (without affecting the wood in any way).
I try to upload some pictures now (I tried to make the chips visible in the pictures). The shaft with 12mm tip has the collar finish oiled up, as seen in the pictures (I have received it this way).
Please let me know on PM if you are interested.
