Cue makers for that has to be a short list.
In looking at it a second time you can see Hoppe on it so it It may be a reworked Hoppe by any number of cue makers. Did Rambow's have Hoppe on them?
According to an article reporting on Mr. Rambow dated July 7th 1967 he did make a cue for Mr. Hoppe (Chicago Billiards Museum). It does not reference any info concerning names applied. So to answer specifically, I don't know. Even if it is refinished or reworked it sure looks like the real deal.
I was actually referring to the cue having the Willie Hoppe stamping like you find on Brunswick Titlist's. This would mean it was made from a Brunswick cue. I was wondering if Rambow used them and did he leave on the signature logo sometimes.
