Window gasket help

[Jkraft]

Here is a new one. The white piece of metal that is on my starboard sliding window fell off. It appears the gasket has failed and it was a compression fitting. Where do I and how do I replace this gasket? Pics attached and photo of it on my port window for reference. The windows are stamped Bomar

Did you ever figure the gasket source out? Mine are also missing that black rubber seal. As a result, the trim pieces just fall off.

my starboard side came off two years ago, the gasket was still in place, I put a small bead of Life Caulk in the channel, put it back on, and jammed a piece of wood against the frame to keep it tight while curing................no problem ever since, I'm keeping an eye on the port side.
