Wish I had Remembered this....
The reason why I questioned whether this was a Palmer shaft is because some years ago I purchased two shafts on eBay that looked identical to the shaft in this auction. They were sold to me as new shafts recently made by an unknown cuemaker.
On the shafts I owned, the darker wood appeared to be stained and on one of the two, the stain bled into the maple. I am not a wood expert, but I am somewhat knowledgeable in woodworking and the shafts I owned were not rosewood, and they certainly were not ebony. The overall finish was only fair which you can see if you enlarge the pics.
I eventually resold them, one at a time, on eBay.
Without good pictures from the current eBay seller, I couldn't be sure whether his was one of the two shafts I had owned and the he wasn't cooperative to provide additional photos or information, other than to say he bought it years ago and didn't remember when or where.
Well, it dawned on me this morning that I might still have pics of one of those shafts on my hard-drive and sure enough, I do.
Whether this recent eBay shaft is one of the two I owned, is open to debate, but comparing the photos of each, they look similar, if not identical.
It is certainly reasonable that Palmer made replacement shafts for someone's Model 20, but to apply that thinking here is to believe all of these are Palmer shafts and if that is the case where's the butt for these? Why are there two (or three)? And they all appear to the new?
Again I wish I remember I had the attached photos earlier.
