I dont know, but maybe this will help,
about 4 years ago, I saw a cue for sale on ebay and I like the style, it had a fiberglass, unique yellow/orange fiberglass shaft with a heavy joint and a heavy metal buttcap. It had a wire wrap around the grip area, which I removed and it was grooved like yours is and has very similar woods. He had a name engraved in the butt, but I thought it was the name of the builder. I put the pictures on AZ, I believe the name was 'Alford' or something like that.
I got some feedback from some of the AZ'ers, they thought he was a WWII Machininist, who put those skills to work to make the cue.,
Let me know if you find the picture and if you think it is the same builder, I still have the cue, but I have never shot with it, it weighs like, 25 ounces or close, put the shaft material was unique and this could tie our cues to the same maker.
I don't remember the makers name being different than the 'alford' that was engraved in the butt area.
Keep me informed and I will let u know if I find out anything, more.

PS. The name on the cue was, ROBERT ALFORD' I think but I will try to confirm. See if anyone else u talk to knows about that name??
