Andersen Operator cover looking to buy 2 new covers

7191-33 written inside part on right and a 6 standing alone on left
Measures 4 5/8" wide, 1 1/16"out from window casing with 7/16" plastic lip that goes into casing and is hidden.




Left hand window also had parts 7168-18 and 7918-8 that I could read.

partial 136... led me to a possible 1361620, but not verifiable

I just replaced two old cracked covers that were stamped "7191-33" with the Swisco 39-154 covers. The 39-154 was a perfect replacement - it actually fit a little bit better than the originals! The only difference I see is that the new ones are somewhat glossy and the old ones were matte (see photo). Made the windows look like new. Thank you, Swisco!
