Your Brunswick pool cue is from somewhere between 1975 and 1985.
It's made from "Indonesian hardwood" with "pearlized and hardwood inlays". They feature a brass-on-brass joint and a ramine wood shaft.
They are considered to be a lower-quality cue because of the quality of construction and the materials used. For example, ramine is generally considered a poor-quality wood stock for a pool cue shaft
I don't have the exact catalog it's from (nor could I find it in the Brunswick Billiards archives), but here's a very close one from the same era. This is from the 1982 catalog. It's also in the 1977 and 1981 catalogs.
In terms of value, the cue isn't worth much. I would put it at somewhere between $40 and $70.
In fact, a few of this exact Brunswick cue model sold recently on eBay. Here's one that sold for $61 at the end of January 2020:
And looking at currently active eBay listings, we see a set of 3 Brunswick cues, from related 1970s / early 1980s Brunswick cue series. They are for sale right now on eBay for $175, and they won't likely get that much.
Here's another similar Brunswick cue (basically the same as yours, save for a few insignificant details), and it is for sale for $175 on eBay right now. Again, they won't get this much for it.
