Looks like you got yourself a true smokers heirloom, great old school. The kind that they still make but it's hard to find the best price. 200 is great for that, I could find that all day and accept it because internal percs were just settling in at this period.
You could say some companies were scrambling to put a label on their products. They did not cheap out on glass. No. They just couldn't figure out how to market something by making it theirs only by design. Some didn't really go that far unless they had an integral part of glass they wanted to "patent" but patents in glass are hard to do anyways. I mean we know a Roor bong by looking at 30-40 percs in there(joking) but hey it's identifiable by any means.
Now it's more of a modern design, put some good functional stuff and label it because it would come from a pretty reputable company and they followed through on a patent design.
I have a deep round bowl bong that's got some nice thickness to it, it sits probably about 20 inches tall clear collar and throat but the base is swirled with some green and white. No design but custom made and it has a viable shape. Only problem is the dumbass that I am clinked the bong not too long ago and now it has a internal crack that does not go to the surface. It's inside and none of the glass moves. This is what separates the good pieces from the cheap because cheap means it chips and easily cracks. Good glass will hold its own and often be considered either surface or underlying damage but it won't cut you or become dangerous if continued to be handled with care.
