I can’t help myself..it’s here. Gsi Creos PS-770. Wow it’s pretty! I’ll be tearing it down in a bit and get a few pics of the parts etc. I do have a question however. How far can I safely tear it down..I know I probably don’t have to but being a former Marine I gotta do it, plus it gets me familiar with it. The head is my biggest concern. Also, never had a Mac valve on any airbrush, do I just open it up all the way and start from there? Here is a teaser pic until later.
