yeah, the pin is in the shaft not the butt. the cue is 10+ years old i don't know what kind of pins dufferins have these days. although i did see some for sale online that looked similar but i don't know how to measure correctly in order to tell which one might fit.
SF is very short on cue experts. i hear there is a place in the south bay but i need to do some more research...[/]
Well it might be time for a new cue

. I am no expert but IMHO it will be hard to find a replacement shaft for that cue, You could have one made but that would cost $100 or more. I think the original company sold out to a Chinese manufacturer several years ago. I have seen three or four different joint types on Dufferin cues but have never seen a male pin like that one in the shaft before. Good luck and let us know how it all turns out.
