Please help identify these vent pulls

Hi. Cleaning up my Dad's estate and have stuff I can't ID. Any help appreciated.
Any ideas what these vent pulls went to. Not sure what the thing on the left is. Only markings are Delco.
Thanks for any help. Uglymailman

 

Black one with V is a chevy' at least a GM early to mid 50s
Round chrome is a 49 Ford.

 

btt for mon people

 

still no ID on the delco

 

The Delco piece is an early radio control head for a component radio where the control head mounts remotely(under dash, on column, etc) and the tuner assembly or tuner/speaker assembly is firewall mounted out of sight. The back of this should have cable sockets for the remote operation of the tuner.
It looks very very early, probably aftermarket rather than specific application but who knows?

 

next stop "PIMP MY SHIT E/GAY"

 

second from the left is 53-54 BelAir...

Yup, over 100 posts of "Id this part please" and strangely enough, they aren't showing up in the HAMB classifieds.
