Well, a lot of styling was wild in the 70's including cues.

Schon are definitely production cues, though they will fill custom orders. I really don't want to get into it over what is custom vs what is not or what is production. Personally, I am not into Schon, do not own one, and I have over 200 cues. The one you posted is particularly ugly with those hideous metal rings in the butt sleeve and the A joint. Those rounded CNC points are hideous. I can't recall that I have any cues with such points. Seriously, with over 200 cues I don't know that I have any with ugly rounded points like that. I have cues made in Taiwan with beautiful sharp pints, perfectly even, even some full splice. Really refined and beautiful next to that ugly garbage. You can, and many do, make sharp points with CNC.
The kind of features you talk about that you don't like can be found on cues made by great respected "biggest name" legendary "custom" makers, as well as various well respected more common makers, and "mass producers". It was the style of the times, like orange or green shag carpeting.
But the styles and design types you are talking about were definitely made, and were definitely available from Adam.
Do you actually want to see them? You will find things like full splice with veneers, real ebony, real wood dashed rings, and other such features you might not like.
