Passenger Car Roof Vents

I am still on the hunt for the vestibule roof vents for streamlined pax cars. It seems that I can find every vent except for those. HELP!!! please

I have posted this topic before but am hoping the right eyes will find this eventually. Thanks

If you’re in Southern Calif or willing to call, Whistle Stop in Pasadena usually carries a lot of passenger detailing parts some I think even uncatalogued.
