I needed a paint gun to paint my primer on the 51 project. I had this old rusted crusty paint gun.. Like an idiot I forgot the before pic, but trust me it was real bad and so rusty ( you can see the pitting on the can arm. ) I did a more satin restoration this go round, looks more well used. And it seems to work very well! This S-70 looks to be a pretty rare model. Closest I could find is a Binks #7 that looks to be similar design.
