The old Dacron wrap needs replacing & I want to go with Irish linen. I need a professional job on it so would appreciate any recommendations on who can do a top notch job. Looking online I note Muellers has been around a long time.
You can't go wrong with Muellers.
It is certainly possible, but your wrap may or may not be Dacron. It could be worn pure black linen.
I attached a couple of pictures for your reference. The first is a Model J in a group with other black Palmers with different wraps to give you an idea of your options. The fourth cue from the bottom is wrapped with nylon. It's impossible to tell in the picture, but nylon has a noticeable weave. The second from the top is a Model 20 with a leather wrap and the bottom cue has a black with white specked linen wrap. The 3rd from the bottom is a Model 9 which had it's wrap removed to inspect the splice in the handle.
The second picture is another Model J with a pure black linen wrap.
The third picture gives you an idea of linen with black specks, and green specks. This is original and no longer available. Today's white/green linen wrap while attractive looks nothing like the original.
Hope this helps.
