That cue was already discussed here in the forums, the owner had asked about it. It is likely from the early 1970's. Probably a Brunswick branded import judging from the numbers stamped on it. The initials were probably added by somebody I think. You can see it is possible the veneers are not real, they may be flaking off. Don't know about the splices. It's a mildly interesting piece to me.
The term "vintage" is actually vague IMHO so I will leave it up to you to decide if the term fits.
