Glazing Strips for Unknown Window Brand

I purchased a house with relatively new vinyl windows installed in the basement. I cannot find any manufacture markings anywhere on any of ghe window parts. I've searched local St. Louis window suppliers and hardware stores for these glazing strips but with no luck. Attached are a couple of pictures and a sketch of the strip. I think it resembles a Swisco 55-204, but mine has a flat area parallel with the surface of the glass and mine is a little larger in both width and depth. I have 4 windows total, but only need 3 long pieces for the horizontal glazing and 2 short pieces for the vertical glazing. If you have any like this, please let me know. And if you think the 55-204 will fit/work, I can install the glazing on windows in opposite walls so it will not be noticeable that the glazing is different. Thanks!
