Paasche needle?

I have a Paasche H-series airbrush that I bought in the early 1980s. The shop I bought it from told me that it had the wrong needle in it for painting models and sold me another one. I still have the "factory installed" needle in a little tube that says H3. I think that H3 is the needle that is currently installed in the airbrush, so my question is:

Is H3 the right size needle for model car painting?
