I have used an old #7 Binks forever, it was given to me buy my uncle in the 60's. He is 75 now. He got it from his Dad, who used it in the Nash Rambler Plant in Kenosha in the 40's. It went through a garage fire in the 70's (melted the cup). It has been rebuilt twice since I've had it. My devilbiss is a primer only gun, but it works pretty good too.
