If legend and memory serves, those were a custom production run by Lewmar, to provide the long-time-classic Ericson Bruce King 'look'.
That option, from an affordable standpoint, probably went away in the 90's.
In modern times there are companies that will routinely make custom aluminum framed boat (and RV) windows. i.e. fixed ports.
There is one company near us,
https://www.motionwindows.com/marine-windows/ , that builds custom portlights, and I know of some boats with their product with the dark safety glass lens, Nice looking but I am not sure that they can bend the aluminum framing material to the sharp angle of the EY - Lewmar trapezoidal ports.
Plan B (strictly IMO) would be to use external lens' like the factory did for the Olson's and that's I have seen some 70's Ericson's where the whole window was replaced. Our boat was spec'd out with Lexan polycarbonate lens' and we have replaced them approx. every couple decades due to hazing. Never a leak, partly due to having no lens-to-frame place for a leak to occur.
The four external lens fixed ports are now in place. Standard on the Olson models, and I note that some older Ericson's have converted to this scheme when their framed ports defied attempts to seal or refurbish them. There is a process to follow...

Note the last picture in that set. They do look awesome and yeah, I would say that.
BTW... if you have an '88 Ericson 32-2, it was built by Ericson Yachts. Or did you mean a 1998?
