Andersen window glazing

Hello,

I have come across your older style Andersen glazing bead in the past. Unfortunately, the part that I used to use to replace it is no longer available but you could consider the 55-023 or Andersen 55-310 glazing bead. These look similar to the one you are looking for. Take a look and see what you think. Thank you.
