ok..am familiar with the Enya nva..with the springy extension..and I know the ST spray bar and the Enya must almost be the same size...but are you saying that Enya has a ST type needle valve also...or you just like the St one...sorry to be confusing the issue....

Is the shipping for things from Japan expensive...seems like there ought to be a source for those old nva except having to get them from across the world...
