Front window sill finishing question

[Kartimel]

This is our 75 Argosy and I have seen many pics of finished campers but just can't see what the window sills look like, so I have nothing to compare this to. It look like something like trim is missing and there are ragged aluminum edges that I don't think Airstream would have left like that when they sold it.
Obviously I need to clean and reseal the window but what about the 'sill'?

I believe my argosy had plastic trim that when over it. Mine long gone so I'm in the same boat as you.

It looked like this. some are saying you can find it online or auto parts store

The windows have a vinyl J Trim sold in 12' lengths, 7.95 each. Get original looking type on vintage trailer supply, but saw different style, I think, on inland rv.

I was expecting something that covered more of the sill but I will search for that piece.
Thanks
