I have two Milgard opening casement windows circa 1995 and the weatherstripping has degraded. I don't see any part numbers on the inner corners of the windows between the panes, but there is a sticker that says: MFGR: MIL-027-1 SERIES: 5420-C MST: 5-3 x 8-1 MVT: 61" x 33"
Are you able to determine anything helpful foe the spacs of the weather stripping from these specs? Thanks.

Attached pictures are of a piece of the weather stripping that is inserted in a channel around the window frame edge (and seals when the window is cranked closed). One picture is a close-up that allows one to see the construct of the weatherstrip. The other picture {pdf) has some notes and measurements.
To summarize, there are no serial numbers of any king on the inside frame of the window (between the panes) or on the glass. On the inside of the strip there is a plastic insert that runs lengthwise down the entire strip. The plastic piece is in the shape of a "T" on its side (but with an extra shorter (1/4") leg on the base - see the left side of the photo being 1/4" and this is the part that slides into the channel in the window. The top part of the "T" is about 3/8ths". The middle of the "T" that connects the 2 ends is the same size as the bottom part (also 1/4"). The remainder of the strip is some kind of flexible outdoor vinyl or other material. Although it was difficult to accurately measure the entire side due to the curvature, it is about 3/4". There was likely some foam or other insulating material inside the vinyl covering.
Please let me know if this helps narrow down what work to replace the original. Milgard (and the two dealers I approached couldn't have been less helpful. End user support at Milgard is non-existent for older products, and without an identifying number, I can't determine if it was sold with a lifetime warranty or a limited warranty. In either case, the house was built in 1995; I bought it in 1997. So I do not have the construction records to determine the specs of the windows/weatherstripping.
MANY thanks for your advice.
