Trigger Question for Norinco Rimfires

[12212012]

I have a CZ 452 and will purchase a YoDave trigger kit for it.
I also plan on buying a Norinko JW25 rifle that uses the same bolt design.
My question is: do the Norincos also used the same trigger design as the 452's?
If they do.... I immagine the kit will work on it too maby.

I've heard the Norinco use the design from a Brno model 1 which is different than the 2,3,4,5 and CZ models.

Brno model 1 was a 2 stage trigger, all the rest are single stage.
