Above is a link to Coast Airbrush - HP-C.  

Unfortunately, the old style HP-C is before the time of YouTube. I do not remember seeing pictures of a breakdown in any of the reviews.

But there are several video of the HP-C Plus. I am not sure how close they are internally.

Don't know if this will help but Don Wheeler has pictures of the parts of a Master G22 which is a copy of the older Iwata HP-C. You can check it HERE

Thanks, Tom. But believe it or not been through pretty much all those videos without finding my answer.

But I really appreciate the quick response.
