Another Mystery Cue ID Thread!

I'm just curious if anyone out there has any idea who may have built this cue:
My father remembers that he won it from another player when he was in college, which was the early 1960's and says even then it certainly wasn't new. I'm confident that mid to late 1950's would be a pretty good estimation for age.

It has a fairly thin brass joint collar with what I'm pretty sure is a 5/16x18 pin going into a shaft with a fairly wide pilot. The shaft is around 13mm, maybe a smidge smaller, and is still straight 50+ years later. The ferrule is not original. The butt is the standard fat diameter of old house cues, and has a ring of minor wear from where it rubbed for years on a rivet that attached the handle to case it rode around in.

The bumper is held on by a standard phillips head with a brass plug/cover that is fairly unique.

All in all I realize it's a fairly run of the mill bar cue conversion, but I'm hoping someone in here may know something extra.

Thanks for the help,

Ah, I completely meant to add that in the first post. He went to both the University of Illinois Champaign/Urbana and Southern Illinois University in Carbondale.
