It would save me alot of extra work if I can refurbish this bib. The threads are .5 inch long, .85 inch outer diameter and the gasket size is .7 inch outer diameter. My home is 1960. Any chance that I can get ahold of one of these to scavenge for parts? I've been epoxying a gasket to the cup for years now, but would like to get it done right. My next alternative is to tap a new screw, but I'd prefer to get the parts, I don't have a drill press. Any ideas?
