The custom cues from California with the "by Castle" inscription are made by a California custom cue maker named Jim Sforza. Apparently he stopped making cues in 1997 or 1998 (though I question that timeline). He did business under "Castle Cues" and worked out of Agua Dulce, CA.

Info on Castle Cues by Jim Sforza
Jim Sforza was trained in cue making by Bert Schrager. According to user "jschaefer" on AZB, Bert trained others e.g. friends and neighbors so that he would have helpers in his own shop.
Bert taught several neighbors/friends to assist him in the shop, Ron Genereax, Frank Austin, and Jim Sforza, who made cues for a short time as Castle Cues.
Most of this info came from a very old sports message board from 2002. Someone said a friend just bought the Castle Cue with S/N 0563, and mentioned it looks to be 10 years old.

It looks 10+ years old, has no points or inlays, but has some pretty nice rings. Has anyone ever heard of this cue-maker?
Post by Jeff, 2002-06-08 10:31PM - There was also a cue maker in California that made cues under the name of Castle, he stopped making cues about 4-5 years ago. His work was very intricate, lots of design and inlay. If I remember correctly, the rings on his cues were mostly diamonds and circles.
Jim Sforza retired from making cues a while back (apparently to focus on making jewelry). When he closed up shop and got out of making cues, Bruce Savolainen at AAA Billiards bought up his remaining custom cues. That explains why AAA billiards has a bunch of them on the site.
Post by Vlad, 2002-06-11 2:11:00 AM - Jim Sforza made cues by the Castle name in CA. My cue has a stylized Castle script with a s/n below in a small ivory window in the butt sleeve. The trim rings on my simple rosewood cue are actual gold dashes in phenolic. Bruce at AAA Billiards in Beverly Hills has the most intricate, incredible collection of his high end cues that I have ever seen. His high end work is well executed and beautiful to behold. I think Jim retired and sold these last cues to Bruce.

Next, I found this Castle Cues custom cue on eBay as of March 8, 2016. It was relisted from a previous auction in January 2016 where it didn't sell. Both times the asking price was $1999.

As you may see in the pictures this is 1 of 1, there is no second example out there. [...] It is used, but in my opinion in very good-excellent condition, to my knowledge it was never refinished. There are 2 shafts with it, one weighs 3.715 oz, the other (shows more use) 4.03 oz, the butt is 14.58 oz. If you are local and would like to check it out in person, please contact us and we will set it up. We are open Monday-Saturday from 10am to 6pm (90035 Zip code).
Also note that in the past, there were two cue makers I know of who made cues under the name "Castle Cues". The other one, who has nothing to do with these cues here, was a cue maker named Rick Castle from Fort Walton, FL. As mentioned earlier, Jim Sforza made cues by the "Castle Cues" name in CA.
I will eventually move this info to a cue maker profile article somewhere here on the site, but for now it can live here in this thread.
