That doesnt look like a SW... Ring work not standard..
Can you get pics of the pin with the serial?
Do you have verification on the cue?
I have the same cue and it def looks the same to me - it's a southwest "pacifier" aka "satin" which refers to the finish not being the glossy automotive finish used on standard southwests.
IIRC, there was just one year when Jerry made about 20 of these that he used pins with the cactus logos. All future pacifiers have pins with no logo or serial numbers.
I think I have this right. Greg, ga9ball can chime in if I don't because he will def know the details. :wink:
