I’m speaking only of the CU22 Soapbar. I had a 1998 model and a 2003 model if memory serves. I don’t recall a neck carve option on that model, but it’s possible.What years were those? When I bought my CU22 in 06, the wide fat neck carve was the most common. There was an occasional wide thin here and there. The CU24 is the model that you would occasionally see the Regular neck carve on. Most had a wide thin in 06. My CU24 has the WT. I also bought that one in 06.
It’s also possible my recollection is faulty. It’s been a long time.
It was available with maple or rosewood fretboard. I had one of each.
