A NOS Hella signal light, 50's bumper guard tie bar & delete plate/ cap to what?

I have 3 more parts I can't seem to ID. I ran these through every google image i could find and all my parts and picture books but can't seem to come up with any matches. Any ideas?

The HELLA signal light is slightly curved and looks like it would go in a valance panel. I checked Hillman, VW, Triumph, Ferrari, Porsche, Fiat, Mercedes and then ran out of Ideas. It has really nice chrome like it may be off a luxury car. The only numbers i can find are BL119 and L so I would assume maybe Left hand side.

The next is a plug or horn button or delete plate of some sort. By the construction I'm thinking it's late 1960's at the oldest but may be up to the 80's. I think it may be Mopar as it came fro ma Mopar dealership. The finish is very good and it almost looks like it has a traces of body sealer on it so I would think it's an exterior plug. The only think I could think of was a filler neck delete plug for a 60's or 70's Dodge truck for behind the seat fuel tanks? That's a wild guess and no images I could find supported it. It's about the size of a gas cap or filler neck though. Maybe even an inbed access plug for an underbed fuel tank?

Last but not least is a NOS bumper guard tie bar or grille guard. By design I would assume it's 40's to about mid 1950's. It came with a load of Studebaker parts but doesn't match anything I can find for Studebaker. There were some Chevy parts from the 53-54 era in with the lot and it seems to follow that design more but it's still not correct. It doesn't appear to be aftermarket. It's very specific the way it fits. It's curved to match the contour of the trunk or grille of the car it's for. It measures 28 and 3/4 not including the 2 little tabs. It's about 2 and 1/2 inches deep. any ideas.

I had to trudge through "Cuba" to find your post. "Studebaker" had me check 1951 accessories.

Your chrome bar looks like the center part grille guard, as illustrated. They offered with or without center. It must have required specific bumper guards in the retro-fit kit.

I appreciate that. I know I'm going to start smoking Cigars if I look at the What is it section much longer. All my Studebaker books didn't show the accessory bar although some did show the wrap around. I probably sold the guards a while back and never knew I had the tie bar. Go figure. Anyways, Thanks again for your help. Now I can get it to someone that can use it.
