Plastic Window part (Trim?)

A handy person from Lakeland, FL says:
I am selling my house and the attached piece is cracked/broken and I have been asked to replace. I cannot find any marking on the windows to indicate the manufacture. The piece is 1/2 x 1/2 x 30 1/2.

Hello,

We can't be sure with the glazing still installed but the 55-194 white vinyl glazing would be a good place to start. Review the specifications below compared to an intact piece removed from your sash. If you notice any discrepancies, get back to us with an end profile photo of your glazing with written-out dimensions, and we'll be happy to confirm if a closer match is available. Thank you.
