Some of the very early history of the predator shaft is not common knowledge. I don't know all of it, but below are my recollections based on magazine reading, internet reading, but anything I have as fact, is based on my personal cues that I have owned. I also do cue work and have cut about 5 of my predator shafts over the years to see the insides. From the 314 in block letters, to the 314-2, they are all the same, except what I wrote about the dimensions of the 314-2 ferrule below.
Something I read somewhere: The very first predator shaft had their hollow shaft design, proprietary ferrule material, but was non-laminated. They then experimented with several lamination designs, I believe 12, 10, and 6. They later settled on 10.
Fact: 1 of the first versions of the shaft had no collar markings (314 marking), and had a 1" long ferrule. A spliced shaft. I own one of these. This version lasted a short period of time in the market.
Fact: Another early version had 314 in block letters, 3/4" long ferrule, and 10 piece spliced shaft. This is the one in the picture above in this thread. This version was on the market for several years. I owned about 10 of these. This was the time period that the "factory seconds" were available, that had a small ring/groove by the joint. These shafts were made in Florida.
Fact: The logo then changed to a cat on the shaft. According to Predator, nothing on the design of the shaft changed here. I owned about 5 or 10 of these. This was also about the same time the Z shaft came out. I don't think they offered factory seconds anymore (speculation). These shafts were made in Florida.
Fact: The 314-2 and z-2 were introduced. They each had a shorter ferrule then their respective prior versions. The ferrule material changed. The way the joint insert was attached to the shaft changed. The manufacturing of the shafts moved from Florida to China. I owned about 10 of these over the years as well. This is the current design still sold.
From a value standpoint, any predator shaft in good shape will bring 80 to 100 easily. When the 314-2 hit the market, many players believed when the manufacturing moved to China, the shaft played differently. So some people were looking for the pre-China shafts. This would include any of the above versions. Some people were paying 150 for a used 314-1. But there are THOUSANDS of them out there. And, I think now most predator users are onto the 314-2, and are happy with them (I know I never felt a difference with the 314-1 and 314-2).
From a collector value standpoint, none of the predator shafts that have 314, a cat, or 314-2 logo on them are worth anything. THere are tons of them on the market, and each version probably had 5 years of production.
From a collector standpoint, I would imagine perhaps the very first versions, with the 1" long ferrule, and the different splice numbers, might be of value. But probably not much.
