Cuetec pin size question

I had a Cuetec jump/break cue butt and both pins in it are 3/8 10. All I see poking around the internet is Cuetec using a 3/8 14 pin. Does anyone know if they commonly used a 3/8 10 pin at one time? I am suspecting that this one is a much older Cuetec cue and they did back then.
The issue came up after selling the butt section on Ebay to someone who was expecting a 3/8 14 pin. Not a problem to resolve with the buyer but I would be interested if anyone knows much about the pin size(s) they have used.
Were there ever any counterfeit Cuetec cues out there perhaps?

Looks like the pin was changed somewhere along the way. The intermediate pin is a 3/8 14 but not the pin for the shaft. Anyone's guess as to why it was changed. Oh well!
