That cue looks like it's from the 1960's. Too bad nobody can seem to get ahold of Dick Helmstetter. He would be a wealth of information because I understand him and Chet Morris were buddies.
I do think Chet made some cues because I have seen other references to him as a cue maker. This cue has the influence of a Doc Fry or Paradise (but it's not) those . The joint has a Viking influence - they sold parts to other cue makers, and Dick Helmsetter and Gordon Hart worked toigether.
I'll try to find more information and get back to you, but I think this cue is a cool find, if nothing else.
